Ancharius

Ancharius refers to a genus of marine ray-finned fish in the family Ophidiidae. These fish are commonly known as cusk-eels. They are characterized by their elongated, tapering bodies, which often resemble eels. Like other cusk-eels, Ancharius species possess a continuous dorsal and anal fin that merges with the caudal fin. Their pelvic fins are typically reduced or absent.

The genus Ancharius is found in tropical and subtropical waters of the western Atlantic Ocean. They inhabit the seabed, often living in soft sediments or near rocky reefs where they can find shelter and prey. Their diet generally consists of small invertebrates and crustaceans.

Reproduction in Ancharius species is thought to involve external fertilization, though specific details can vary. The eggs are typically demersal, meaning they sink to the bottom. The larval stage is pelagic, drifting in the water column before settling to the benthos.

Currently, only one species is recognized within the genus Ancharius, Ancharius gryllus. This species is distributed along the coast of North and South America, from the Carolinas down to Brazil. While not a target of commercial fisheries, they may be caught as bycatch. Information regarding their conservation status is limited, but they are not currently considered endangered. Further research is needed to fully understand their ecological role and population dynamics.
