Phyllidiopsis is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs and is the largest genus within the family Phyllidiidae.[1]


Description

The species in this genus differ from the other genera in this family by possessing an elongate foregut and fused oral tentacles.[2]

Distribution

These nudibranchs can be found in the tropical Indo-Pacific region, the eastern Pacific region, in the Red Sea, in the Caribbean Sea and a few in the Northwest Atlantic Ocean. About half of the described species can be found in deep waters. Among these deep-water sea slugs, there is a group of white species, lacking all contrasting colors.[3][4]

Species

There are presently about 30 species in the genus Phyllidiopsis including :[1]

Species brought into synonymy

A maximum-parsimony analysis of the nucleotide sequence of the 16S mtDNA gene, performed in 2003, has shown that the genus Phyllidiopsis is paraphyletic.[12]
