I am in the lucky situation that I get to dive on Negros Island in the Philippines almost every week, and the more time you spend underwater with a camera, the more unusual and interesting action you'll get to film. This week we saw a hairy frogfish on a feeding frenzy, having some shrimp...

It's my pleasure to introduce a scuba related book my friend Dr. James Reimer and myself wrote: 25 Future Dives. We explain environmental problems in the form of dive briefings: coral bleaching, plastic trash, invasive lionfish, and many more. We also have a few "fun" chapters, such as the one...

I am taking a different approach to popularizing marine biology of the "muck" fauna here: instead of explaining all I know about the biology of the animals I film underwater, I ask questions about them which come to my mind. All filmed on Negros Island in the Philippines, in sand and seagrass...

I am lucky enough to be able to night dive on Negros Island regularly. The sand/soft bottom habitats ("muck") are unsurpassed imo. These days the water is so rich in plankton that it feeds a lot of the critters the Philippine muck diving is famous for. This week, during a single dive, we saw...

All dives are nice, but in some there is more action than in others. Last week an eel knocked my camera out of my hand, and I witnessed a wrestling match between two crabs, plus a fire worm feeding on a crab. Negros Island, Philippines, at night. Enjoy:

Good news: It was my TG6 which experiences a leak, and it's fine. But, I would like to understand what was going on. I had in fact cleaned the o-ring and grove before the dive, re-lubed with original Olympus grease, and re-inserted. I do a lot of beach dives, so there is some fine sand on the...

I'm happy to be back on Negros Island, and have had some reasonable success filming the muck diving world of Dauin and of adjacent Zamboanguita. For your viewing pleasure: Goby behavior, a robust ghost pipefish, and a waspfish: I always enjoy spotting a waspfish, very cryptic. Then, I came...

Small fish larvae have difficulties feeding because of the hydrodynamics at such small sizes. This likely explains their high mortality. The physics of this problem the fish face are not trivial, and we try to explain them with some humor. An analogy which is sometimes used is that the feeding...

A team led by Dr. Rene Abesamis, UP Marine Science Institute, led this year's survey of the coral reefs of Apo Island, Negros Or, Philippines. The survey investigated the fish diversity & biomass and the coral cover. Surveys of Apo have been running for 40 years now, started by the late Prof. A...

I had a bit of free time lately to shoot some of the underwater wildlife here in Dauin in the Philippines. Number one, I now have figured out how to always find these basket stars during night dives in "Luca Sanctuary". There are three individuals of them, two large ones and one juvenile. I...

Well, the insights are at least new to me: The well known sardines are not just sardines (but there are several species of them!), but also jackfish. My friend, fish biologist Prof. Kent Carpenter, explains which species are present. Also: likely human run-off brought the fish there in first...

I made a video about the bobtail squid. There is excellent science about it and its symbiotic bacteria, which seem to spread around the world in a different way than the cephalopod itself. I shot the footage off Negros Island (Dauin and neighborhood) in the Philippines with an Olympus TG6. Enjoy!

I made a video explaining the taxonomy, feeding & defense behavior of sea slugs and how they mate. The video is meant an an introduction to marine gastropods. I explain how nudibranchs are related to other sea slugs. I illustrate my points with footage which I shot in the Philippines over the...

I had the opportunity to participate in the survey of reef fishes in Tubbataha on invitation of the Tubbataha Management Office. We were on the last trip of the season, in late June. There was some rain, but generally the diving conditions were excellent, even though this is considered late for...

I put together an infographic about where to dive in the Philippines, given what you'd like to see, wrecks, critters, reefs, or walls. I also note of the site is best/only dived by live on board, and if there is nightlife to be enjoyed. I have been to most (not all) of the places I list, any...

Ladies & gentlemen & mermaids, for your entertainment, my new footage from the last 2 months of night diving off Negros Island in the Philippines. Conditions were brilliant lately. Lots of interesting crabs, a school of shrimpfish liking my video lights, tiny scorpionfish juveniles, also very...

I am in the lucky position that I live close to an excellent muck diving site, on Negros Island, in the Philippines. During night dives, the crustacean biodiversity is amazing. The video below is from a night dive this week, and shows how even a small area can be home to multiple species of...

A new video of mine, quite stoked about an interesting interaction between two critters I managed to film: A small crab got caught in the tentacles of an anemone at night in one of the typical muck diving sites of Negros Island in the Philippines. It’s quite interesting to see how cleverly the...

I’m excited about the release of my first full-length documentary: “Muck: The Biology of Underwater Sandy Habitats in the Tropics”. The footage is the result of my underwater filming throughout most of the pandemic, and the narration is a result of years of thinking about the “muck” fauna as a...

We have to talk about harassment of ROVs by scuba divers. This can’t go on like that. Some of these ROVs will not be able to work through the trauma they are put through by these divers. Filmed in Sagay, Negros Island, Philippines.
