It is dorso-ventrally flattened with an undulating wavy margin, which is formed into a pair of tentacles at the anterior end.

The mouth is on the underside and the gut divides into many anastomosing branches that take nutrients to all parts of the body.

Small batches of eggs are laid in gelatinous masses and develop directly into miniature adults.
