Baeolidia australis

World Register of Marine Species | Encyclopedia of Life | Wikipedia

Baeolidia australis
(Rudman, 1982)

Baeolidia australis is distinguished from Baeolidia moebii by having a thin orange sub-apical band above a broad blue band on each ceras, which is never present in Baeolidia moebii. Baeolidia australis looks bluish whereas Baeolidia moebii is more yellow or brown. The body of Baeolidia australis also seems to have a brown and white reticulate pattern that is not found in Baeolidia moebii.
