Description

The spearfish remora is a remora (family Echeneidae) occurring worldwide in warm oceans. The species reaches about 50 cm and has an elongate body with an oval sucking disc on the head, a modified dorsal fin with which it attaches to larger animals. It lives almost exclusively on the body and in the gill chamber of billfishes and swordfishes, and sometimes in the mouth or gills of sharks. In this way it hitches a ride and feeds on skin parasites and food scraps from its host. The species is harmless to humans and of no fishery value.
