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.

Common characters are also two wide longitudinal yellow-greenish stripes usually separated by a narrow black median line.

The bright and contrasting colors serve as a warning for predators to not eat this inedible species.

The species is a hermaphrodite, meaning that they have both male and female reproductive organs.
