Bassanago nielseni is an eel in the family Congridae (conger/garden eels). [2] It was described by Emma Stanislavovna Karmovskaya in 1990, originally under the genus Pseudoxenomystax . [3] It is a marine, deep-water dwelling eel which is known from the central and southern part of the Nazca Ridge, in the southeastern Pacific Ocean. It dwells at a depth range of 160–340 metres.

Eel order of fishes

An eel is any ray-finned fish belonging to the order Anguilliformes, which consists of four suborders, 20 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage, and most are predators. The term “eel” originally referred to the European eel, and the name of the order means “European eel-shaped.”

Congridae family of fishes

The Congridae are the family of conger and garden eels. Congers are valuable and often large food fishes, while garden eels live in colonies, all protruding from the sea floor after the manner of plants in a garden. The family includes over 180 species in 32 genera.

Marine biology The scientific study of organisms that live in the ocean

Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

The species epithet was given in honour of Jorgen Nielsen, a specialist in the study of deep-sea fish. [2]

In zoological nomenclature, the specific name is the second part within the scientific name of a species. The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description.
