Anilao is known as the nudibranch capital of the world and for good reason. Not only are you apt to find a nudi on every dive, but its very likely that you can find a different nudi on every dive (or several different nudi’s). In 2013 I got my first chance to dive Anilao, in Batangas, Philippines, as a trip leader for Bluewater Photo. Nervous, as it was my first time leading a trip… let alone my first ever international diving trip, it all ended up going very well. We had a great group of guests, really enjoyed the resort (Crystal Blue), and my co-leader, Ron, was excellent.
I had heard tales of the variety of life found throughout the Anilao region and had perused through some fish and invertebrate ID books prior to the trip but was still floored by the incredible biodiversity found on every dive. This region varies from beautiful coral reefs to seemingly barren, sandy muck dives. The knowledgeable guides really make the trip, as they know where to find unique critters and help you discover all the treasures hiding throughout the dive.
I love the various colors, shapes and sizes of nudibranchs found throughout the world and getting to dive in Anilao was amazing. Here are just a sample of what I saw throughout my (too short) week diving with the hundreds of nudibranchs in Anilao. (I tried to ID them properly, but if I am incorrect, let me know in the comments!)
Marionia sp. 5 or 6
Chromodoris willani (aka “Sparkle Butt”)
Ranging in size from extremely small to bigger than my fist, one of the most enjoyable parts of diving in Anilao was searching for as many different nudibranchs as I could find. It was easy to spot the Choromodoris annae as they stand out and can often be found out and about. The better camouflaged ones were often spotted by the incredibly talented guides, who know where to look and what to look for. More often then not, the guide would point at a nondescript section of reef and it would take me a few moments before I could discern the nudibranch from the surrounding environment. These of course were often the most unique sightings, and usually the ones most difficult to photograph well.
One of my favorites from Anilao is the Chromodoris willani, which I dubbed “Sparkle Butt” as its gills were speckled and looked like they sparkled. In addition to that, the Ceratosoma alleni was incredible primarily for its size and unique shape, though easy to miss despite being nearly 5 inches long as it camouflaged well with the surroundings.
There are so many more incredible nudibranch and other critters from the Philippines, way too many for one simple post, but I figured this would be a great place to start.
