Biology     Glossary (e.g. epibenthic)

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).

IUCN Red List Status (Ref. 115185)
