They are very active in confinement and will crawl out of uncovered dishes. The prostomium is broadly rounded, with 3 tentacles and evertible nuchal organs which appear when the animal is moving. There are two pairs of eyes, the outer ones larger than the inner.

In some cases in the preserved material this pigment completely obscures the eyes, while in others the smaller pair only are inv
