A dull cream to fawn seaslug, with many compressed cerata (outgrowths of the body), which appear to cover the entire upper surface of the body. It has oral tentacles and rhinophores (sensory “horns”) and two scythe-like tentacles at the front corners of the foot.

An uncommon species found at the very low tide level.

Probably a predator.

Rolls up when disturbed.
