The teeth sit outside of the mouth, interlocking, with two large lower fangs that curl upward reaching past the fish’s eyes. Because its jaw can unhinge, the viperfish can eat large prey for its ...
Ranging in color from dark gray to dark brown, deep-sea species have large heads that bear enormous, crescent-shaped mouths full of long, fang-like teeth angled inward for efficient prey-grabbing. Their length can vary from 2–18 cm (1–7 in), with a few types getting as large as 100 cm (39 in), [ 15 ] but this variation is largely due to ...
The Giganturidae are slender, slightly tapered fish with large heads dominated by large, forward-pointing, telescoping eyes with large lenses. Their heads end in short, pointed snouts. The highly extensile mouth is lined with sharp, slightly recurved and depressible teeth and it extends well past the eyes.

Ceratiidae was first proposed as a subfamily of Lophiidae in 1861 by the American biologist Theodore Gill, [1] with Ceratias as its only genus. [2] Ceratias had been proposed as a monospecific genus in 1845 by the Danish zoologist Henrik Nikolai Krøyer when he described Ceratias holboelli from the waters off Greenland.
