Species Felimare tricolor (Tricolor doris)

These nudibranches have an elongated and smooth body of about 3 to 4.5 cm. Its foot is narrow, but the front is rather rounded. Colour is dark blue to violet blue. It presents a broad yellow or whitish longitudinal line in the middle of its back. The top of the mantle has also white spots more or less visible.  The edge of the back has a yellow line, but this does not cover the foot, which present a white or yellow line. In between the edge and the middle lines it shows a longitudinal thin white line, sometimes yellow, sometimes discontinuous. Rinophores present horizontal flaps, usually with a white tip. Gills are arranged forming a plume on the back, these are tinged with a thin whitish line.

Often confused by Felimare orsinii, but these are small, have thinner and fine white and yellow lines, and lack of white discontinuous stripes between the edge and the median line.

Can be also confused by Felimare fontandraui, but these show some transparency on its blue body, its median line is more irregular, and rinophores and gills are larger than in F. tricolor.

Felimare villafranca can also be confused, these have much finer white, yellow or even orange longitudinal lines, sometimes forming a network all over its back.
