Overview
The daggertooths (genus Anotopterus) are a genus of aulopiform fish, the sole genus of the family Anotopteridae. They are found in oceans worldwide, but prefer cooler waters.1]
Daggertooths are similar to the related lancetfishes in appearance, with a large mouth and dagger-like teeth. However, as their scientific name (meaning "without fins on its back") suggests, they lack the large dorsal fins of the lancetfishes. They grow to as much as 147 centimetres (4.82 ft) in length.
Species
Only three species of the family and genus have so far been formally described:[2]
Family Anotopteridae
- Genus Anotopterus
- Anotopterus nikparini - North Pacific daggertooth
- Anotopterus pharao
- Anotopterus vorax - South ocean daggertooth Regan, 1913
A possible fourth species was discovered in 2008, but has yet to receive a taxonomic name.[3]
