The bull relatives (Cottales) are a group of real bony fish in the rank of subordinate or partial order (and not to be confused with their superior Cottoidei (Cottimorpha / Cottiformes)). These fish live in cold seas around the world, and the Cottus genus also lives in the fresh waters of the northern continents. In the Siberian Lake Baikal they make up a large part of the fish fauna. According to the traditional system, the bullheads of Lake Baikal form their own families, the Baikal group (Cottocomephoridae), the Baikal oilfish (Comephoridae) and the deep water group (Abyssocottidae). However, they are phylogenetically within the genus Cottus .
Traditionally, the bull relatives were placed in the order of the " armored cheeks " (Scorpaeniformes). However, there are strong indications of a close relationship with the eel mother relatives (Zoarcoidei), so that Wiley & Johnson merged both subordinates into the order Cottiformes.
features
The Cottales synapomorphies include four large spines on the skull in front of the gill cover , the loss of the fourth pharyngobranchial bone (top bones of the gill cage) and the sphenoid bone (base phenoid) as well as the demersed eggs (sinking to the ground). The eggs of the "armored cheeks", on the other hand, are planktonic . H. Imamura and M. Yabe give a total of 13 synapomorphies for the bull relatives.
Systematics
In a current system, nine families are assigned to the Cottales:
- Partial order Cottales
- Panzerroppen (Agonidae)
- Bullheads (Cottidae)
- Sea hares (Cyclopteridae)
- Jordaniidae
- Disc bellies (Liparidae)
- Dickkopf bullheads (Psychrolutidae)
- Rhamphocottidae
- Scorpaenichthyidae
- Trichodontidae
