Ancula gibbosa, common name Atlantic ancula, is a species of dorid nudibranch. It is a marine gastropod mollusc in the family Goniodorididae.

Distribution

[edit]

This species was described from the Mediterranean Sea at Nice, France. It has a wide distribution from there along the Atlantic coast to Norway, Greenland, Iceland and across to New England on the coast of North America. Ancula pacifica apparently has a number of colour varieties which closely approach this species and is currently believed to be a synonym.[4]

The nudibranch Ancula gibbosa, Rathlin Island, Northern Ireland.

Description

[edit]

This goniodorid nudibranch has a translucent white body with yellow or white tipped processes.[5]

Ecology

[edit]

Ancula gibbosa feeds on Ectoprocta. It has been reported to possibly feed on a variety of sessile organisms, but these are just the substratum to which the ectoprocts are attached.[5]
