Cryptobranch Dorid Nudibranchs

The cryptobranch dorid nudibranchs include several families that vary in morphological characteristics. Except for Hexabranchus, all are able to retract their gills into a gill pocket, completely hiding it, hence the name cryptobranch (hidden gills). Like the chomodorids, which are also cryptobranchs, all are thought to be sponge eaters. Most live hidden under rocks or in other dark areas during the day, and some emerge at night to feed. Many species are small or nondescript, and many of these are not easy to identify. It is likely that there are some as yet undescribed species in the list below.
