Phanerobranch Dorid Nudibranchs

This list of phanerobranch dorids contains species from several families. Many of these species are small and often stiff, so they tend to be slow moving. Most are not commonly found, but that could be due more to their small size and slow movements than to any inherent rarity. Many of them were found only by turning over a rock and staring at the underside for several minutes before some of the small, cryptic species gave themselves away by slowly starting to move away from the light. Other species, such as the Nembrotha spp, are much larger and faster, and are often quite easy to see. Most likely most of these larger, more flamboyant species are toxic or distasteful to predators, and their bright colors and more exposed lifestyle may warn potential predators that this particular morsel is not edible.
