(Bergh, 1880)[1]

Hypselodoris peasei is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.

Taxonomy

It was originally named Doris prismatica var. lineata Pease, 1860, but lineata was already used for Doris lineata Eydoux and Souleyet, 1852, so Bergh (1880) provided the replacement name Chromodoris peasei. Bertsch and Johnson (1989) erected the name Hypselodoris andersoni for the locust nudibranch, unaware of Bergh's earlier name. However, Gosliner and Johnson (2018) recognized that C. peasei matched the description of H. andersoni, and formalized the priority of Hypselodoris peasei over H. andersoni.[1][2]

Distribution

This nudibranch is known only from the Hawaiian islands of Oahu and Maui in the central Pacific Ocean.

Description

Hypselodoris peasei has a white body and a blue mantle edge and foot. There are often black specks present on the upper dorsum. The gills and rhinophores are white, lined with orange bands.

This species can reach a total length of at least 20 mm and has been observed feeding on yellow sponges from the genus Luffariella.[1]
