The swimming goby ( Gobiusculus flavescens ) is type of goby that lives in the sea and brackish water of the European Atlantic coast , especially in the area between the Faroe Islands and Norway to the Spanish northwest coast , in the southern Baltic Sea , on the British coasts and possibly in Mediterranean occurs. The fish becomes a maximum of 6 cm ( TL ) long.
habitat
The goby lives in dense grassy areas and is mostly in overgrown buildings and seagrass and Seetangbänken found. They mostly live in the mudflats and in shallow water at a depth of up to 20 meters.
description
The swimming goby is a small, narrow type of goby with a maximum size of 6 cm. They differ from other gobies in that their eyes are on the side of their head, as opposed to others in their family who have these on the top. Their species is characterized by a black spot on the bottom of their caudal fin , but males have a second, smaller black spot between their pectoral fins . Their color ranges from reddish to green-brown, but is paler on the underside and has a reticulate pattern on the back. Along the center line is a series of bluish markings that become extremely light in males during the breeding season.
Way of life
In contrast to most gobies, this species does not live on the seabed, but instead populates the seagrass and seaweed in schools. It feeds on zooplankton , such as the larvae of various crustaceans . Breeding takes place during the summer. The male borders a territory in the sand, usually under a stone, in which the female lays her eggs. The male protects the eggs until they hatch. The fry move into deeper water to spend the winter there, while the adults usually die before they can reproduce a second time.
