Cadlina is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks historically classified in the family Chromodorididae.[1] Recent research by R.F. Johnson in 2011 has shown that Cadlina does not belong to the family Chromodorididae.[2] She has therefore brought back the name Cadlinidae from synonymy with Chromodorididae. The family Cadlinidae also includes the genus Aldisa Bergh, 1878.[2]
