The Striated Aglaja has a large body that varies widely in color, from brown to dark gray or olive, and is covered with fine pale lines or small speckles. It has two side lobes on its head and two matching pointed tails. A visible row of small blue spots runs along the edge of its body flaps.

This Headshield Slug can be found on sandy or rocky bottoms in shallow waters. It moves slowly and stays close to the bottom, actively hunting and tracking its prey, which includes other sea slugs, especially bubble shells and nudibranchs. Like many sea slugs, each individual can act as both male and female during reproduction. A notable fact is that the Striated Aglaja is known to engage in cannibalism, sometimes eating smaller members of its own species.
