Catriona gymnota is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusk in the family Trinchesiidae.[2]

Distribution

This species was described from Massachusetts Bay, on the Atlantic Ocean coast of the US. It is reported from the NW Atlantic from Canada to New Jersey.[3] DNA evidence suggests that the NE Atlantic specimens previously thought to be this species actually belong to a separate species and should therefore be called Catriona aurantia.[4][5]

Description

This species has a translucent white body and slightly swollen cerata. The digestive gland is orange pink in colour and the tips of the cerata have a broad white band of tiny epidermal glands. In larger specimens the rhinophores develop a pale orange suffusion. The foot is broad and rounded anteriorly. Large individuals may exceed 20 mm in length.
