Ardeadoris cruenta

Ardeadoris cruenta

''Ardeadoris cruenta'' is a species of very colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae. Its name is derived from the feminine form of the Latin word ''cruentus'', which means "stained with blood" and is a reference to the red spots on its upper dorsum. It was transferred to the genus ''Ardeadoris'' on the basis of DNA evidence.

''Ardeadoris cruenta'' has a pale-lemon colored body with a bright yellow and white lined frilly mantle and foot. There are red dots in a circular pattern on its dorsum next to the mantle edge. Both its rhinophores and gills have the same pale-lemon color as its body, although there is some color variation among individuals. It reaches a length of at least 50 mm.
This species has similar coloring to the seaslug ''Ardeadoris rubroannulata'', although that species lacks the red dots present in ''Ardeadoris cruenta''.
