生物学特性     字汇 (例如 epibenthic)

Oceanic species with a semi-obligate commensal relationship with sharks, rays, other bony fishes and turtles (Ref. 5217). Young are usually associated with jellyfish and drifting seaweed (Ref. 2850, 9563). Feed on scraps of host's left over, parasites and excrement; also on small fishes and invertebrates (Ref. 5288). Eggs are pelagic (Ref. 4233). Marketed fresh and salted or dried (Ref. 9283). Captured at the surface using hand nets (Ref. 26165).
