Benthophilinae

Kessler goby

The Benthophilinae are a subfamily of gobies. The subfamily was in 1927 by the Russian ichthyologists D. Beling and BS Ilyin set up, but the associated genera later attributed to the subfamily Gobiinae. 2009 Benthophilinae were newly diagnosed by Neilson and Stepien as an endemic in the Pontic and Caspian region Grundelunterfamilie.

Dissemination

The small freshwater and brackish water species of fish are on the banks of the Black, Azov and Caspian Sea and in the inflowing rivers. Five species of this subfamily spread in recent decades over Central Europe and could colonize other basins, such as the Rhine. Two types of Benthophilinae came through the ballast water of ships in the North American Great Lakes and now there are the most common ground fish.

Features

The Benthophilinae are small to medium sized gobies. Her license plate include sensory papillae, which are in six to seven rows below the eyes, tubular anterior nostrils, which are located near the back of the eye sockets, and upper pectoral fin rays, which are surrounded by fin membrane. A swim bladder is absent. The eggs are medium to large in size and contain little yolk. A pelagic larval stage is absent. From the subfamily Gobiinae to the genera of Benthophilinae were previously counted, the Benthophilinae can be distinguished mainly by the number of vertebrae. They have a total of 28 or more vertebrae, of which 18 to 22 caudal vertebrae (all vortices behind the anus).
