Description

The smooth sandeel is a very slender, eel-like marine fish of the family Ammodytidae reaching about 30 cm. The streamlined, silvery body has a greenish back, a pointed head with a projecting lower jaw and, unlike many relatives, a largely scaleless, smooth skin. The species lives on sand and gravel bottoms in coastal water of the north-eastern Atlantic and the North Sea and forms schools above sandbanks. It is notable for being able to burrow into the sand at lightning speed to escape predators. It feeds on zooplankton such as copepods and fish larvae. Sandeels are an important food source for seabirds, marine mammals and commercial fish.
