Colorful Dirona

Dirona picta

Description 8

Varying from green to orange, this sizable slug is relatively common in our area, but can be quite difficult to spot, since it looks almost exactly like a piece of algae. While there are few slugs that look even remotely similar, the inflated cerata covered with tuburcles are probably the best trait to look for. Behrens and Hermosillo (2005) report that it ranges from Cape Meares, Oregon south to Isla Ángel de la Guarda in Baja, as well as the Sea of Japan.

Distribution 9

This marine species occurs from Northern Oregon, USA to Baja California Sur, Mexico. Also reported from Japan.
