TGIF – Those Pesky Nudibranchs

Under the Laha dock in Ambon is not the most scenic dive site in the world, but what an amazing place for critter watching. This seahorse, pointed out by my friend Wendy McIlroy, looked like it was eating a nudibranch. Theoretically nudibranchs exhibit aposematic coloration, bright colors that warn would-be predators that they are toxic or distasteful, but maybe this seahorse was colorblind. Once I settled down and focused, it was obvious that the little flabellina wasn’t breakfast – it was a hitchhiker!
