| Sabertooth fish (also spelt sabretooth) are small, fierce-looking deep-sea aulopiform fish comprising the family Evermannellidae. The family is small, with just eight species in three genera represented; they are distributed throughout tropical to subtropical waters of the Atlantic, Indian, and Pacific Ocean.

These fish are appropriately named for their oversized, recurved palatine teeth redolent of the sabertooth cats. The family name Evermannellidae was given in honour of Dr. Barton Warren Evermann, a noted ichthyologist, naturalist and director of the California Academy of Sciences. The palate is the roof of the mouth in humans and vertebrate animals. ...

Physical description Sabertooth fish have moderately elongate and compressed bodies which lack normal scalation. The head is large and blunt; the terminal mouth is large, and it is lined with slender palatine teeth, the frontmost of which are greatly enlarged and curve inward slightly. A number of shorter, straighter teeth accompany these fang-like teeth. The tongue is toothless. The eyes range in size from small to large; they are tubular in structure and point upwards. The lateral line runs uninterrupted. The vertebrae number 45–54 and there are three discrete bands of muscle tissue (epaxial, midlateral, and hypaxial) present in the caudal region. The air bladder is absent and the stomach is highly distensible. In most biological nomenclature, a scale (Greek lepid) is a small rigid plate that grows out of an animals skin to provide protection. ...

The gas bladder (also fish maw, less accurately swim bladder or air bladder) is an internal organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth, ascend, or descend without having to waste energy in swimming. ...
In anatomy, the stomach (in ancient Greek στόμαχος) is an organ in the alimentary canal used to digest food. ...
There is a single high dorsal fin (with 10–13 rays) originating slightly before the thoracic pelvic fins. The anal fin (26–37 rays) is the largest of the fins, and runs along the posterior half of the fish, tapering in height towards the emarginate caudal fin. A small adipose fin is also present. The pectoral fins (11–13 rays) are positioned rather low on the body. All fins are spineless and lightly pigmented in shades of brown. Dorsal Fin of the Orca A dorsal fin is a fin located on the backs of fishes, whales, dolphins and porpoises. ...
Fish anatomy is primarily governed by the physical characteristics of water, which is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs light more than does air. ...

Sabertooth fish are usually a drab, light to dark brown when preserved; however, a brassy green iridescence is seen on the flanks, cheeks, and ocular region of well-preserved specimens. The naked skin is easily torn. The Atlantic sabertooth (Coccorella atlantica) is the largest species, at up to 18.5 centimetres standard length. The iridescence of the Blue Morpho butterfly wings. ...
Life history Almost nothing is known of the biology and ecology of evermannellids. They are active, visual predators and confine themselves to the mesopelagic zone, ca. 200–1,000 metres down; they are most commonly trawled from between 200–400 metres. At these depths there is extremely little to no light; the view from below is like the sky at twilight. The sabertooh fish use their telescopic, upward-pointing eyes—which are thusly adapted for improved terminal vision at the expense of lateral vision—to pick out squid, cuttlefish, and smaller fish that are silhouetted against the gloom above them. Main articles: Life All organisms (viruses not included) consist of cells, which in turn, are based on a common carbon-based biochemistry. ...

Their distensible stomachs allow sabertooth fish to swallow prey larger than themselves; their recurved teeth likely function in a manner similar to a snake's, preventing a captured fish from backing out and helping to guide the fish down the sabertooth's pharynx. Sabertooth fish are solitary animals; it is not known whether they undergo diel vertical migrations.

Their reproductive habits are poorly studied; they are assumed to be non-guarding, pelagic spawners. True synchronous hermaphroditism with external fertilization is known in Evermannella indica and Odontostomops normalops, and the former species appears to spawn throughout the year. Sabertooth fish larvae are planktonic and have long snouts and oblong eyes before metamorphosis. Both larvae and juveniles remain at shallower depths of 50–100 metres, descending to deeper water with age. Reproduction is the biological process by which new individual organisms are produced. ...
