Where seen? This small black slug is sometimes seen on some of our shores, burrowing among seagrasses and near living reefs.

Features: 1-2cm. A long, cylindrical body that appears to be made up of two parts. A pair of 'tails', one a lot longer and narrower than the other. It has a tiny internal shell. Included here are slugs that are all black and those that are black with speckles and other touches of colour.
