Headshield slug

Aglaja tricolorata


Headshield slugs, or cephalaspideans, are a primitive group of sea slugs closely related to the well known nudibranchs. They have a shell which is covered by the flaps of the mantle and lack the rhinophores which are so distinctive on nudibranchs. They also possess several sensory cilia on the anterior end and spend most of their time burrowing through the sediment.


17 meters deep.
