The body is elongated and oval, with a velvety dorsal surface, a grey-black ventral side and quite short pseudo tentacles formed by folds of the anterior margin. All individuals of the ''divided flatworm'' have a black body with an orange margin. Common characters are also two wide longitudinal yellow-greenish stripes usually separated by a narrow black median line. However, this species of ''Pseudoceros'' is highly variable in color and in pattern, in terms of the arrangement and width of the various transverse stripes and of the width of the longitudinal stripes. It can take at least three different types of liveries. The bright and contrasting colors serve as a warning for predators to not eat this inedible species. These flatworms feed exclusively on colonial ascidians. They are also cold blooded.
