Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Adults inhabit rocky shores (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
