The saw bass ( Serranus cabrilla ) is a medium-sized sea fish from the family of saw bass (Serranidae). It lives in the entire Mediterranean , in the western Black Sea and in the eastern Atlantic from the coasts of the British Isles to South Africa , as well as the Azores , Madeira and the Canary Islands . Occurrences in the Red Sea are uncertain.
features
The perch can be a maximum of 40 centimeters long, but usually remains at a length of 25 centimeters. Its body is spindle-shaped and elongated. The basic color is light, dark or red-brown. Specimens living in caves or other shaded areas tend to be reddish, animals that tend to stay in sunny locations tend to be brownish. On the flanks it has seven to nine transverse bands, which are interrupted by a white or yellow longitudinal band that extends from head to tail. Its dorsal fin is supported by ten hard rays and 13 to 15 soft rays, the anal fin by three hard and 7 to 8 soft rays.
Way of life
The perch is territorial and true to location. It lives at depths of 5 to 500 meters on the shelf in rock reefs, seagrass meadows and over muddy or sandy seabeds and feeds predatory on small fish, cephalopods and crustaceans . Like all saw bass of the genus Serranus , it is a simultaneous hermaphrodite ( hermaphrodite ), i.e. it has functional male and female gonads at the same time . It is not known whether self-fertilization is possible. In the Mediterranean the fish spawn from April to July, the population in the northern Atlantic a little later.
