Nudibranchs are so colorful for a variety of reasons, to warn predators and to fool them, for camouflage, and because some have toxins which can taste bad to predators. Many can incorporate stinging cells from the anemones they eat, while others hijack the poisons from the sponges that they ingest. Thankfully for the snorkeler we are most interested in locating, observing, and photographing them so simply th fact that they ARE extremely colorful makes for a bit of an underwater treasure hunt when trying to locate these small (most are less than 3-inches) critters. Below are photos showing some of the slugs we encountered on the most recent Oceanic Society snorkel trip to Raja Ampat in Oct/Nov of 2011.
