Baptodoris
Baptodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
The genus Baptodoris was originally classified by Bergh in 1891 in the subfamily Platydorididae (despite the use of suffix -idae), a subfamily of the family Dorididae. In 1934 Alice Pruvot-Fol elevated this subfamily to its new status as family Platydorididae. In 2002 Valdés has given the name Discodorididae precedence over the name Platydorididae.
The Sea Slug Forum however classifies this genus in the family Dorididae.
