Biología     Glosario (por ej. epibenthic)

Facultative air-breathing (Ref. 126274); Adults occur in intertidal reef flats, benches, and rocky shorelines exposed to strong wave action. 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).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Oviparous, distinct pairing (Ref. 205).
