The stomiidae or stomias (Stomiidae) are a more than 270 species in 28 genera in all oceans, including the Mediterranean , widespread family of deep-sea fishing . They include (according to the traditional view) the well-known viper fish ( Chauliodus ).
features
The animals have an elongated body, the head and mouth are large. The unequal teeth are dagger-shaped, curved backwards and protrude when the mouth is closed. The scales fall off easily and are dark, brown, or black. The animals have luminous organs , partly also in the mouth and gill cavity. The animals are 4 to 50 cm long. They can also (in relation to their own size) prey very large, e.g. B. sardines , overwhelm. The genera Aristostomias , Eustomias , Malacosteus , Pachystomias and Photostomias can put their head back further than all other bony fish and open their mouths up to an angle of 120 °. This is made possible by an additional, cartilaginous joint between the back of the head and the first vertebra.
- Subfamily Astronesthinae
- Subfamily pangolinfish (Stomiinae)
- Subfamily viper fish (Chauliodontinae)
- Subfamily scaly dragonfish (Melanostomiinae)
- Subfamily black dragonfish (Idiacanthinae)
- Subfamily Malacosteinae
According to current phylogenetic studies, the bearded dragon fish are not a monophylum , because the viper fish are more closely related to the deep-sea hatchet family than to the other bearded dragon fish examined. The subdivision into subfamilies made here does not seem to exist in this form either.
