The crocodile toothfish ( Champsodon ; Greek champsai = crocodile, odous = tooth) are a genus of small marine fish. They occur in the tropical and subtropical Indo-Pacific at depths of up to 0–1120 meters.
features
Crocodile toothfish grow to be three to four inches long. Their ventral fins are elongated like a flag and are located in front of the small pectoral fins. The first dorsal fin, supported by fin spines, is short and high, the second, with soft rays, is long. They are supported by a total of five hard and 17 to 20 soft rays. The anal fin has no fin spines and 17 to 20 soft rays.
Systematics
Both by Near and employees as well as by Betancur-R. and colleagues, the crocodile toothfish could be the sister group of a clade formed from the sand cave fish (Creediidae) and the Hemerocoetidae .
Tribal history
The extinct relative Eochampsodon is known from the Eocene of the northern Caucasus .
