Tentacles on nasal opening, above eye and on nape near first dorsal fin ray. Dentaries joined by suture. Lateral line reduced, discontinuous. Anterior part of dorsal fin conspicuously higher than posterior part.
Body shape (shape guide): elongated.
Adults are found over hard bottoms. Mainly nocturnal, they feed on small invertebrates. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Eggs are laid under mussel-shells or stones and guarded by the male (Ref. 5981). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Spawn in April (Marseille) or July (England) (Ref. 5981).
