Where seen? This small slug was seen at Cyrene in a sandy area near seagrasses and reefs.

Features: 2-3cm. A long, cylindrical body that appears to be made up of two parts. A pair of 'tails', one a little longer than the other. Dark body with tiny pale yellow spots. Flaps on the front and back of the body with black margins and larger pale blobs.

What does it eat? Some species eat bubble shell snails, hunting them by following their slime trail then swallowing them whole.
