जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Facultative air-breathing (Ref. 126274); Adults are found in tidepools (Ref. 54980). 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).
