| Occurs along the entire northern coast of Europe to Germany, Denmark and Great Britain. In the seas of the Mediterranean basin and the Black Sea. Small species (up to 31mm), leads a secretive lifestyle. It occurs in the coastal zone to a depth of 30 m, on sandy and silty-sandy soils, sometimes in thickets of zostera. Digs holes 0.5-1 m deep (Kobyakova, Dolgopolskaya, 1969). The existence of this species in the Black Sea was first established by M.A. Dolgopolskaya based on materials from the Sevastopol Bay. Larvae at different stages of development and several adult specimens were captured (Dolgopolskaya, 1954). But these materials have not survived (Kobyakova, Dolgopolskaya, 1969). | ||||
