A distinguishing feature is the triangular bright white patch located between its oral tentacles and rhinophores.

Habitat and Geographical Range

Infrequently found on pilings along the eastern Pacific coast, the Grey Sea Slug inhabits coastal waters. It prefers environments where it can feed on the tentacles of anemones and other cnidarians.

What They Eat and How They Breed

Grey Sea Slugs primarily feed on the tentacles of anemones and other cnidarians. They reproduce sexually, with fertilization occurring internally. The females lay egg masses, which hatch into larvae before developing into adult sea slugs..
