जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Found in the intertidal zone on coarse-grained (Ref. 104171) sandy beaches (Refs. 104348, 104171). Some migrate up and down the beach with the tides (Ref. 104348). Actively migrates by jumping out of the sand and riding specific waves (Ref. 104171). Filter-feeder (Ref. 104245). Feeds on phytoplankton, algae, detritus, bacteria and other small suspended particles via its short siphons (Ref. 104246).

Semelparous species (Ref. 104352). Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
