Physical Description

Most free-living flatworms have a very bright and characteristic coloration pattern, which turns to be the main identification parameter (Newman and Cannon, 1995). They can be as colorful as nudibranchs and are sometimes confused with them because of that (Newman et al., 1994). Pseudoceros prudhoei has a dark brown almost black dorsal surface and a lighter ventral surface (Fig.2C). The margins of the body have two colorful bands: the inner is blue and the outer is yellow (Fig.2A) (Newman and Cannon, 1994).

As all the organisms that belong to the family Pseudocerotidae, P. prudhoei has a very flattened oval body with pseudotentacles. These tentacles were named like that because they are simple upfoldings of the margin of the body (Fig.2B). Another characteristic of the group is that the pharynx is located at the anterior part of the animal (Fig.2C) (Newman and Cannon, 2003).
