Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Circumtropical in tropical seas. Western Atlantic: Nova Scotia, Canada to Argentina (Ref. 7251). Eastern Atlantic: British Isles (rare vagrant) and Bay of Biscay to Angola, including the Mediterranean and Canary Islands. Eastern Pacific: Vancouver Island (British Columbia, Canada) to the Galapagos Islands (Ref. 2850). Common throughout the Indian Ocean (Ref. 3197).

Biology     Glossary (e.g. 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).
