The body is tough and rigid, and ranges in colour from lemon yellow to a pale brownish white, made up of a translucent background colour and a close scattering of fine pigment spots. There are also some large scattered greyish brown spots, each edged with a ring of the opaque background colouration. There is a low rounded median dorsal ridge which widens posteriorly to form a trilobed gill cover, and anteriorly it spilts to form a raised rhinophore pocket on each side. There are few stalked dorsal tubercles, as found in other species of Aegires, but there are low some rounded bumps scattered over the dorsum. In Atlantic specimens there is a distinct lateral ridge, or mantle edge, down each side of the body. It grows to approximately 12 mm in length.

It is reported to feed on the yellow sponge Clathrina coriacea [Ros, 1977 - Canary Ids] and Clathrina sp. [Thompson, 1981 - Bermuda].
