Ophidiiformes (Cusk-eels)
Scientific Classification
Class: Actinopterygii (Ray-finned Fish)
Superorder: Percomorpha
Order: Ophidiiformes (Cusk-eels)
Ophidiiformes are an order of ray-finned fish which include cusk-eels, brotula and pearlfish. These bottom-dwelling marine fish are characterised by their long, slender bodies with both dorsal and anal fins.
Ophidiiformes evolved during the Late Cretaceous. Ampheristus is the only described member of this order within the Eocene, London Clay and represents one of the earliest known members of this order.
This image shows an extant Brotula cusk-eel, a modern relative to Ampheristus.
