Fiji – Yasawas Part 3 – Night Snorkel & Bull Sharks

May 7, 2026May 6, 2026Leave a comment

Fiji Village

Although I spent most of my time in Fiji in the water, I did take the opportunity to visit a local village during my stay. Many of the people who worked at the hotel I stayed at came from this nearby village. We had a tour guide for our visit and he said that a lot has changed since the resort was built. Walking around town, there were solar panels providing electricity to many houses as well as backup water tanks. Most houses had moved their kitchens indoors out of the rain. We were able to peek inside the local church, medical offices, and school but none of these were in session.

The most interesting thing for me was the lali drum in the center of the village near the church. When it is hit, it makes a deep resonant sound that calls villagers in for meetings or to celebrate an event. Lali drums are still used today and continue to play an important role in Fijian culture and traditions.

Night Snorkel

I had already done a night dive, but I figured I could squeeze in at least one more night adventure at the next place I stopped. It ended up being a good one. I saw a Partridge Tun Snail that was over a foot long and slowly making its way along the seafloor. Their main source of food is sea cucumbers which are also much more plentiful at night. There were also a couple of turtles and reef sharks ominously swimming around us. Every so often I’d catch a glimpse of a tail or a fin. Reef sharks are generally not aggressive and they feed on tiny fish and crustaceans. They seemed to be mostly curious about the group of humans in the water while keeping their distance.

Sea cucumbers come out in force in the evening hours. I continue to delight in all the shapes, sizes, and textures that they come in. They are so strange and loveable, looking like giant blobs making their way ever so slowly across the ocean floor.

The one in the photo below is a bit smaller, but while in Fiji I saw a Graeffe’s Sea Cucumber that was over two feet long. During the same night snorkel, our guide also managed to spot another day octopus out and about after dark. I’m beginning to think this species needs a new common name, although plenty of people insist they do see them during the day as well. At first glance, the Lion’s Paw Sea Cucumber looks almost like a snake lying on the seafloor. Once it starts moving, though, it resembles a wrinkled, expandable garden hose slowly inching its way across the ocean floor.

Fish

To be honest, I’m generally not that into fish. Some species, like the lagoon triggerfish (also the state fish of Hawaiʻi), are relatively easy to identify because their patterns are so unique and distinctive. When I first started snorkeling, I often felt overwhelmed trying to identify and name different species. After each trip, I would go home, download my photos, and carefully upload them to iNaturalist so I could learn their names. That approach was genuinely helpful. I began to recognize different fish shapes and groupings, even if the specific species names did not always stick.

In many ways, that is still how I think about fish. Does it fit into a group I already recognize? Or does it stand out as something distinctive? Are the patterns interesting? Does it have an unusual color pattern or a unique shape? Any of these traits might prompt me to reach for my camera and pay closer attention when identifying it later on iNaturalist.

There is no single right way to learn about sea life. It is perfectly fine to snorkel or scuba dive and simply appreciate the beauty of coral reefs without knowing any names. For me, learning some of their names adds another layer of enjoyment. Names open the door to a deeper understanding, giving me access to each species’ story, behavior, diet, and role within its ecosystem.

Giant Clams

These giant clams also have a symbiotic relationship with dinoflagellates, just like the corals I mentioned in the last blog, a relationship known as photosymbiosis. The phytoplankton carry out photosynthesis and produce sugars that provide about 60-70% of the energy the clam needs to function. The rest of its diet comes from particles it filters out of the surrounding water.

The clam has two openings in its mantle: the incurrent siphon, which it uses to draw water in, and the excurrent siphon, which it uses to expel water. In between, it filters detritus and plankton from the water and transports them to its mouth for digestion.

Bull Shark Dive

The first time I snorkeled with a California Leopard Shark I remember how my breath caught just for a moment, before my brain could remind my body to calm down and just enjoy the experience. Leopard Sharks are harmless, but much of the media surrounding sharks has turned all sharks into feared creatures far out of proportion to the actual risk they pose. We are about 50 times more likely to die from being struck from lightning than being attacked by a shark.

Nonetheless, I’ve had to learn to manage my fear and recognize real risk versus perceived risk. The black and white reef tip sharks in the photos above rarely ever attack humans. There are a handful of records of them biting humans, but generally they are shy and remain apart from divers.

There are however three species that account for the most shark attacks: Great White Sharks, Tiger Sharks and Bull Sharks. I have absolutely no interest in cage diving with Great White Sharks, but one resort in Fiji has been offering daily Bull Shark dives for over two decades, and I signed up.

Bull Shark (with two remoras close by)

Remoras are interesting fish with a suction-disk on top of their heads that allows them to attach to the undersides of larger animal. They eat the leftover morsels that the sharks don’t grab, as well as waste 💩 that comes from their hosts.

Bull Sharks have the scientific name Carcharhinus leucas. The first part comes from the Greek karcharos which means sharp and rhinos which means nose. Leucas from the Greek word for white which apparently refers to their white underbelly.

This dive is very different from regular scuba dives. The dive starts with a swim over a shelf and then descends to a viewing platform. All the tourists crouch on their knees behind a rock wall and everyone has a bodyguard standing behind them. Each bodyguard has a metal pole that ends in a triangle shape (see photo below). They use this pole to gently guide the shark away from the tourists when they get too close. Once everyone is ready, other staff members start feeding the sharks fish heads. Tours happen twice a day and the sharks are really good at showing up for meal times.

In the picture above, the male shark’s claspers are also visible. For whatever reason, male sharks have two organs that can be used to inseminate a female shark. They only use one at a time during intercourse, apparently whichever one is more convenient based on which side they are on.

The sharks did get very close and often swam right next the divers. I thought the whole experience was magical and surreal. There were several giant sharks swimming around me, but inside I just felt completely calm. I felt safe and protected by my bodyguard and just very lucky to have the experience.

more shark close-ups (notice the hook on the shark’s mouth)

This video doesn’t fully capture the experience, but it at least gives a small taste of what it was like. (I recommend watching it in full screen.) Also, I want to give a big thank you to the scuba staff photographer who taught me how to properly use white balance at depth so my photos are finally coming out much closer to their true colors.

Fiji – Yasawas Part 2 – Coral Reefs

April 26, 2026May 6, 20261 Comment

Coral Reefs

I slowly made my way down the Yasawas, stopping at a couple resorts along the way back to the main island. It is impossible to capture how stunning it is to swim out from shore and be surrounded by yards of coral reefs in crystal clear waters.

Although corals can grow in a variety of environments, most coral reefs are found between 30°N and 30°S latitudes. Corals are small animals that capture and eat plankton using stinging cells, similar to jellyfish. However, they also host a type of symbiotic plankton called dinoflagellates. These dinoflagellates perform photosynthesis and produce sugars that corals use for energy to grow, build, and survive. In return, corals provide the dinoflagellates with a safe place to live.

A single coral structure contains hundreds of genetically identical individuals living together as a colony. This cooperative structure allows them to sustain themselves and build the protective coral skeleton that shelters the entire colony. Corals require abundant sunlight and nutrient-poor water to thrive. When nutrient levels rise (particularly nitrogen, phosphorus, potassium, and iron), algae can flourish, overgrow the coral, and block the sunlight they depend on for survival.

coral reefs stretching forever

The beautiful colors of coral reefs come from the dinoflagellates living within them. When ocean temperatures rise too high, the chloroplasts in these organisms become stressed and release oxygen. This oxygen damages the coral’s cells, and the coral expels the dinoflagellates for behaving badly. This process is known as coral bleaching, and such events are becoming more common as ocean temperatures continue to rise in these regions.

Blackback Butterflyfish with corals, Cauliflower Coral, Black-axil Chromises

If the water cools down in time, corals may allow the dinoflagellates to return. However, if the water remains too warm for too long, the corals can become permanently bleached. This is because corals obtain up to 90% of their energy from their symbiotic plankton and often die when that energy source is lost.

Bicolor Blenny, Fiji Tomato Clownfish, Moorish Idol

Coral reefs cover less than 1% of the ocean floor, yet they are among the most important ecosystems in the ocean because they serve as nurseries for many species. They provide shelter and protection where young organisms can hide and grow until they are large enough to fend for themselves.

Orangestripe Triggerfish, Bridled Monocle Bream

Corals are considered to be foundation species, because the entire coral reef ecosystem wouldn’t exist without their skeletons. These animals create an area that allows all these other organisms to thrive.

Blackspotted Puffer, Specklefin Grouper, Longnose Filefish

The corals in these photos are part of a Marine Protected Area. In this case, this means that people cannot fish or remove species from the area. As fish and other organisms mature within the MPA, they gradually move into surrounding waters, where they can help repopulate other regions or become part of the food web for humans and other animals. Marine Protected Areas allow organisms, especially fish, to grow large enough to reproduce and sustain future generations.

Invertebrates

As always, I went out looking for nudibranchs, and although there weren’t very many, I did manage to find a couple hiding between the corals.

Pustulose Wart Slug, Blue Linckia, Krempf’s Phyllidiopsis

Giants clams of all kinds continue to be my other favorite invertebrate find. The patterns on their mantles are intricately colored and vary dramatically between individuals.

Muck Dive

I had heard rumors of some tiny nudibranchs down in the sandy bottoms, so I signed myself up for a muck dive. This is basically looking through sediment for weird, camouflaged organisms. I didn’t find any nudibranchs unfortunately, but I did see transparent shrimp and this tiny, patterned anemone attached to a blade of seaweed.

Sarasvati Anemone Shrimp, Swimming Anemone, Banana Coral

The most ridiculous muck dive find was a giant yellow sea cucumber that was over two feet long. Sea cucumbers feed on detritus (poop and decaying organic matter) from the ocean floor. They ingest sand, digest the organic material within it, and then get rid of the remaining sand out of their back end. Nearby was evidence of its recent activity, a large mound of sandy poop that was at least a foot across.

Fiji – Yasawas Part 1 – Cool Caves and My First Night Dive

April 12, 2026May 6, 20261 Comment

I went to Fiji in November of last year, but I’m finally getting around to writing it up. The next few posts are heavy on the photo dumps, which seems to be my default when I spend most of my vacation in the water.

Sawa-I-Lau Caves

For this trip, I headed to the Yasawa Islands arc that stretches up in a curve from the western side of the main islands. At the very top are the Sawa-I-Lau caves. Tourists are only allowed in the first two caves, the rest are considered sacred and only locals may enter them. To get from the first cave to the second, guides helped me swim through a six-foot underwater tunnel. One gave me a big push while another pulled me out on the other side, so all I really had to do was hold my breath and kick. It was a bit nerve-racking going in, but easier on the way out since I could swim toward the light. This island is made entirely of limestone, while most of the surrounding islands are volcanic. For me, the most interesting part of the caves was a freshwater eel swimming in the brackish water. I asked a lot of questions about it, but no one had any answers, only assurances that it would not hurt me.

While waiting to take the boat back to the hotel, I found a cute little pipefish in the sandy bottoms. These are related to seahorses, but have a different body shape. Some people get these confused with the tiny eels that live in sandy bottoms (that I saw later on this trip), but they really do have distinctive postures and head shapes. That purple blob in the photo caught my attention too. At first I thought it was a soft coral, but when I got closer I could see it was covered in tiny tentacles. It is always fun to come across organisms that look completely different that what you expect.

Snorkeling and Scuba Diving – Nacula Island

I went to Fiji because I got a great deal on a direct flight and because it’s at the very edge of the Coral Triangle. I’m always looking for nudibranchs and figured I would find a few. While there, I also decided to get my Advanced Open Water certificate so that I can dive slightly deeper dives (up to 30m / 100ft). I ended up being the only student on this trip, so I had a personal guide who helped me spot all these beautiful sea slugs. I had to learn how to do compass navigation and a variety of other skills, but after those were finished, it was all about taking cute photos of underwater life.

Sky Blue Phyllidia, Striped Phyllidiopsis, Baby Sergeant Major Fish

In addition to nudibranchs, there were also a bunch of flatworms which are also extremely impressive and come in a variety of shapes and colors. The one in the middle was surreal and only a few inches long. We looked it up in dive book and although the genus is known, it’s still an undescribed species (or was when the book was published).

Sapphire Flatworm, Pseudobiceros sp., Family Pseudocerotidae

Sea stars also come in an amazing variety of shapes, sizes, and textures. All three of these were new to me!

Indian Sea Star, Egyptian Sea Star, Thousand-Pores Sea Star

In addition to all the diving, I also did a fair amount of snorkeling. The corals next to the resort were pretty shallow and most of the days, the waves were calm. Usually I think of algae coming in red, green and brown varieties, so it was a bit of a shock to see the yellow one below. It looked like an underwater succulent in bloom. This species actually grows quite tall, but this one was just a baby. For the record, even though it was yellow and green, it does, in fact, belong to the brown algae family.

Ornate Turbanweed, Sea Grapes, Pennyweed

Here’s a small selection of fish from snorkeling. The more time I spend in the water, the more different species start to reveal their distinct personalities. I’ve seen porcupinefish all over the world, but they are almost always tucked underneath rocks or along reef walls. If you get too close, they retreat further into hiding, but otherwise they tend to stay in one place, quietly watching and waiting. On the other hand, flashy surgeonfish are zipping around all over the reef like they can’t stay in one place. The morays are always wedged into the rocks, mouths open waiting for something to swim by.

Spotted Porcupinefish, Striped Surgeonfish, Snowflake Moray

Of course, there was coral everywhere and this yellow fan coral stood out because of its bright coloration.

Knotted Fan Coral, Lithophyllon concinna

However, the star of the show was this color-changing coral. These belong to the genus Cladiella and the coral retracts its feeding polyps when it’s touched, which causes its color to change.

Blushing Corals (genus Cladiella)

My First Night Dive

As part of my Advanced Open Water certification, I asked to do a night dive since I had never done one before. I’ve always enjoyed night snorkeling because all kinds of critters come out at night that don’t appear during the day. While waiting for my boat to be ready, the Fijian sunset was incredible. #nofilter

absolutely stunning Fijian sunset – on the way to the night dive

Eventually, my guide and captain sailed us over to the dive site. This was, by far, my favorite dive of the entire trip. Diving at night, illuminated only by bioluminescence and flashlights, is awesome. Here are my top three favorite photos from the dive, especially the one in the middle. Bubble coral is pretty easy to see during the daytime, but the pointy tentacles underneath only come out at night. The clam on the right is actually bioluminescent, and I wish we had turned off our flashlights to see its colors. However, to get that photo, my guide was illuminating it from below, and I was upside down, holding on to a rock, attempting to get my camera into position inside a hole. The fact that we got a photo at all was kind of a minor miracle.

Bushy Feather Star, Bubble Coral, Electric Fileclam

The site is called the Cabbage Patch because of the huge scroll coral. It’s hard to picture how large these piles of corals are, but the giant rosettes are easily two to three times the size of a human. During the day, all kinds of life hang out inside the whirls, but at night, the parrotfish settle in for a nap.

In addition to the sleeping fish, I found an octopus, which ironically is known as the Day Octopus because it’s one of the few octopus species that is actually diurnal instead of nocturnal. The manta rays also get more active at night; this one was roaming all over the place. During the day, these are usually nestled into the sand.

High up near the top of the cabbage coral, we found this foot-long crab crawling along as we were doing our safety stop near the surface. Earlier, I’d found the cool green and purple urchin and my guide had spotted one of the fried egg nudibranch species.

Sawedged Spooner Crab, Globe Urchin, Phyllidia Nudibranch

I still have no idea what kind of cnidarian is in the first picture below. It looks a lot like the tentacles on a bubble coral, but could just as easily be an anemone. If one of you knows what it is, please leave me a comment. I also saw my first night anemone. My guide didn’t know what it was, so it was fun to be able to identify something for him. Although it’s a super blurry photo, it was exhilarating to see a siphonophore up close. I teach about these in my Marine Biology class and they really are a strange group of colonial cnidarians. They are made up of multiple individual organisms working together as one colony. Some parts help it to feed, some parts keep it afloat, but all of the parts share nutrients and resources. The Portuguese Man O’ War is probably the most commonly known siphonophore, but I always imagine them looking more like the one below.

Anemone or Coral?, Night Anemone, Siphonophore

I wholeheartedly recommend night diving. It’s definitely worth the hassle and cost. Well, that about sums up my first stop in Fiji, more photos of marine life coming soon. 🙂

Xiao Liuqiu

This mini island (off the main Taiwanese island) has a bazillion spellings of its name, but regardless of the name, going there had to be one of my favorite parts of the trip. We were there during Thanksgiving, which was just a regular week day in Taiwan. Our first stop was renting scooters. Chalida was a bit fearful of the scooter, so she ended up on an e-bike and her daughter Rory climbed on board behind me. The first day, we went snorkeling and had a delicious BBQ dinner, with Chalida’s friend Nate joining us. The day of Thanksgiving, I got up early to go scuba diving (more on that below), while the rest of the group slept in. That afternoon, Cassy had a special request that we go to karaoke and after a slow start, everybody got into it.

The whole time we were there, we ate so much food, drank so much boba, explored so many beaches, and saw so many green sea turtles.

Taiwanese Food

Here’s a glimpse of some of the food we ate. Most of this was from Xiao Liuqiu, but some of it was from earlier and later in the trip.

Scuba Diving

I figured that one of the best ways to keep my fears in check is to keep doing something regularly so the fear isn’t allowed to grow. I checked iNaturalist to see what nudibranchs were around and one of my favorite species had previously been spotted near the island. I definitely wanted to try to find it. It is a beautiful sea slug that looks like its entire back is full of butterfly wings (Cyerce nigricans). I signed up for two dives on the island and had my guide to myself on the first dive. I told her I loved nudibranchs and she asked if I knew how small they are and I assured her that I did. All of these were under an inch small, so she did a great job of finding these.

Black and Gold Sapsucking Slug, Pustulose Wart Slug, Black Margined Nudibranch

I’m still in love with giant clams, and there were plenty of those to see. The colors and patterns on the inside of the shell are so beautiful.

There were also a range of semi-transculent underwater gems.

Florideophycean Algae, Clark’s Anemonefish, Tunicates

We have purple sea urchins in the United States, but white ones aren’t that common. Also, as mentioned earlier, there are green sea turtles all over this island. It’s practically impossible to get in the water and not see one.

Indo-Pacific Rock Boring Sea Urchin, Porcelain Anemone Crab, Green Sea Turtle

I actually found the eel in the picture below. I got my guide’s attention to show her, but I really didn’t know the hand signal for eels, since I’m so new to diving. I gestured for her to come over and she was excited that I found it. The signal is to stick your fingers and thumb out and then bring them together so it looks like the mouth of an eel eating.

Since it was getting close to Christmas, I took some time to capture these Christmas tree polychaete worms. If they get spooked, they disappear back into their tubes, so you have to approach slowly and carefully and stay a bit of a distance away. I realize they don’t look much like worms, but the rest of their bodies are hidden inside the tubes.

Christmas Tree Worms: white, red, and blue

Kaohshiung

While the rest of the group headed back to Taipei, I stopped for a day in the city of Kaohshiung. It’s way more laid back than Taipei and had a lot of nice bike trails. The first night I wasn’t up to doing too much, so I walked along one of the rivers in town to check out the artwork and fancy buildings.

art sculptures near Pier 2, Kaohshiung Music Center lit up in Christmas colors

The next day I got up early and headed out on some bicycle explorations. As I was biking along the river, I stopped to watch a dragon boat race competition. I visited another Hakka Museum that had more information than the one we had visited in Taipei. I also went to the Art Museum and headed over to a flea market full of the most random items: sculptures, rocks, wooden bowls, mannequins, books, antiques, food, cheap souvenirs. It was a total hodgepodge of items, just like flea markets everywhere I suppose.

Cijin Island

Cijin Island is a cute micro-island off the big island of Taiwan. After all of my other explorations, I took a ferry across to the island and then rented a city bicycle to ride the beautiful bike path going from one end to the other (about 15 km round trip). There’s a bunch of art sculptures along the way, as well as one super windy spot where people were flying kites. I made sure to stop in at Douliu Ice Town to try one of their peanut ice cream sandwiches before I got back on the ferry. I grabbed my backpack from the hotel and lugged it to the train station and hopped on the high speed train back to Taipei.

Here’s the second blog post filled with marine creatures from Indonesia. Remember you can click on an any image if you want to see it in more detail. First up are the arthropods – lots of crabs, shrimp, and lobsters.

And now, a cute collection of clownfish.

Clark’s Anemonefish, Spine-cheek Clownfish, Ocellaris Anemonefish

Followed by some cuttlefish and a turtle. Most cuttlefish I’ve seen in aquariums are quite small, but these are a couple feet in length. They are incredibly still and you could swim right by one and not even notice. In fact, on my first dive I saw one and grabbed my guide’s leg to get his attention. He thought I was in some kind of distress, but quickly calmed down when he saw the cuttlefish I was fangirling over.

Needle Cuttlefish, Unknown Cuttlefish, Hawkbill’s Sea Turtle

There were also rays and eels.

Bluespotted Fantail Ray, Common Moray, Oriental Bluespotted Maskray

And lots and lots of fish.

Twinspot Blenny, Many-host Ghostgoby (with parasites), White-spotted Puffer

The crocodile flathead was a new one for me and I have so many questions about how the flap of skin over its eyes help or harm its vision. The harlequin sweetlips swims like a bat out of hell (see video below). My guide Maja took the photo of it where it looks so calm and I still have no idea how he did it, because it almost never stops moving.

Food

In Jakarta, there were always plenty of vegetarian options, but on Derawan Island, there was a lot less choice in general because the island was so tiny. However, I found a few places that offered up rice and noodle dishes that were meat-free. I ate a lot of tempeh while I was there for protein.

Scuba Diving in Sangalaki – Part 1

January 11, 2025January 12, 20251 Comment

After getting my scuba certification while I was still in graduate school, I never went diving again. I did my certification dives in cold Monterey, California and when they had me clear my mask, it freaked me out to have my nose in such freezing water unable to breathe. I kept popping up to the surface because my weights were off and, at the time, I decided it was an expensive sport that I couldn’t really afford anyways.

However, when I was planning this trip, I realized I probably was just hiding behind my fears and I should try and tackle them. I booked a five-night stay on Derawan Island with scuba dives planned for three times a day with a private refresher lesson on the first day. I definitely was nervous and uncomfortable and right before we were supposed to go down, I had a very clear moment of “oh, hell no, I’m not doing this.” However, I was able to take a bunch of deep breaths and calm down and my very patient scuba dive instructor Maja helped me get through my initial moment of panic. Funnily enough, as soon as I was underwater, I was fine. I’ve been snorkeling for years and have all the underwater practices of clearing my mask and breathing through my mouth.

Fear is a lurking ghost that hides inside us, haunting our actions, until one day, we push through it and it’s just gone. As soon as I realized I could do it, and how beautiful it was down below, the fear vanished and instead, I was able to just enjoy all the beautiful scenery and marine life. I still struggled to adjust the air in my BCD and it was hard for me to stay still. But those are skills that come with practice and I was already improving in my few days of diving.

view from my above-water bungalow

The next couple of blog posts are just lots and lots of pictures of cool marine life. Remember you can click on an any image if you want to see it in more detail. This post is mostly sea slugs, which is why I ended up in Indonesia in the first place. The Indo-Pacific Ocean has some of the most colorful and diverse varieties of nudibranchs in the world, and I’m positively obsessed with them. Some of these photos are mine, some of them are from Maja.

First up are some lovely tunicates. These are all invertebrates, but they are in the Phylum Chordata because they all have the beginnings of a rudimentary spinal cord called a notochord. They are the invertebrates that are most closely related to humans and these in particular were very colorful.

Golden Sea Squirt, Green Barrel Sea Squirt, Rhopalaea fusca

Next up are some lovely echinoderms: one sea cucumber and five sea stars. The variation in shape, size, color, and texture in sea stars is incredible.

Lampert’s Sea Cucumber, Spinose Feather Star, Pebbled Sea Star

Granulated Sea Star, Blue Linckia, Genus Nardoa Sea Star

This is what a sea cucumber looks like when it’s feeding. It uses its mouth parts to bring sand and the detritus it eats into its mouth. Eventually most of the sand comes out the other end and scientists think that at least half the world’s sand has traveled through the digestive tracts of sea cucumbers.

I’m a big fan of giant clams. They are huge, always a surprise, super colorful and patterned on the inside flesh.

Boring Giant Clam, Boring Giant Clam, Fluted Giant Clam

Next are a couple of sea slugs that aren’t nudibranchs and a sea hare, which is pretty closely related to the sea slug family.

Blue Velvet Headshield Slug, Lovely Headshield Slug, Aplysia nigrocincta (Sea Hare)

And now, for the stars of the show: the nudibranchs! These are different from other sea slugs because of the two rhinophores they have on their forehead. They use them for sensing the world around them.
