The anal fin has one hard and 14 to 16 soft fin rays. The pelvic fins are on the chest. A total of 52 to 57 scales lie along the sidelines .

distribution

The earfish can be found in the northeastern Atlantic from the Kattegat over the North Sea and Great Britain to North Africa and in the western Mediterranean .

Way of life

Spearfish live as schooling fish in the coastal area at depths of up to 20 meters, where they occasionally invade lagoons and the brackish water of estuaries. They are mainly found in the surface area and feed on fish larvae and plankton organisms .

The breeding season of the fish extends from April to July. The 1.8 to 2.0 millimeter large eggs are released into the open water and hook onto algae and stones with fine threads. The larvae hatch with a length of about 7 millimeters. The maximum age is around 4 years.
