Hypselodoris carnea explained

Hypselodoris carnea is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.^{[1] [2]}

Distribution

This nudibranch was described from Île aux Fouquets, Grand Port, Mauritius. It is frequently reported from South Africa, along the KwaZulu-Natal coast but these animals differ considerably from the original description.^{[3] [4]}

Description

Hypselodoris carnea has a flesh-red mantle with six (rarely five) longitudinal white lines, white spots and carmine spots between the lines. The edge of the mantle is yellow-red. It was described as reaching a total length of 22 mm alive. There is wide range of colour variation reported for this species and South African animals have many white lines instead of six, suggesting a species complex. It is said to be easily mistaken for Hypselodoris capensis^[5] and perhaps species of the Hypselodoris maculosa complex.^[6] It feeds on sponges.
