Appearance

This species can grow up to a length of 6 cm.
The background coloration of the body varies a great deal, from light orange-brown to black or whitish to cream in color. The body is always marked with dark or clear spots, according to what is the dominant background color.
The mantle, which covers the body, is composed of four distinct parts: dorsal, anterior, and two lateral pieces protecting the gills. These lateral pieces are on the right side of the body; they have the same coloration as the body, but are outlined in black.

Three of its dorsal parts can be shed in case of danger, a form of autotomy. This species has another means of defense by secreting a repellent acid fluid.

The head has a pair of smooth and slightly folded rhinophores. A trapezoid veil masks partially the oral cavity.

The egg ribbon is whitish.
