The two-spotted goby (Gobiusculus flavescens) is a species of goby native to marine and brackish waters of the eastern Atlantic Ocean where it can be found from the Faeroes and Norway to the northwestern coast of Spain. It has also been recorded from Estonia though records from the Mediterranean Sea are uncertain. They are common on all coasts of the United Kingdom.

Description

Gobiusculus flavescens are small, slender gobies, reaching up to 6 cm in length. They are distinct from other gobies in that their eyes are on the side of the head (lateral) rather than on top (dorsal). There is a black spot at the base of the tail fin, and in the males, there is a second, smaller black spot beneath the pectoral fins. They are reddish to greenish brown in colour, paler on the undersides with dark reticulations dorsally. There are four light 'saddle' marks dorsally from the head to the end of the second dorsal fin. Along the midline of the sides are a series of bluish markings. During the breeding season these markings become extremely bright in the males.

Behaviour

Unlike most gobies, this species does not live on the seabed but instead lives in shoals among seagrasses and seaweeds. It feeds on zooplankton such as crustacean larvae. Breeding takes place in the summer. The male becomes territorial and scoops out a nest in the sand, usually under a stone, in which the female lays a batch of eggs. The male then guards the eggs until they hatch. The juvenile fish move into deeper water to spend the winter. The adults usually die after reproducing once.
