Description

The crystal goby is a very small, almost transparent goby of the family Gobiidae reaching about 5 cm. Unlike most gobies, which live on the bottom, the crystal goby drifts freely in the open water; its glass-clear body makes it almost invisible in the water. The sexes differ: the male has large canine teeth and a sturdier build than the slender, transparent female. The species lives pelagically above the continental shelf of the north-eastern Atlantic, the North Sea and the western Mediterranean. Hovering in the water it picks small zooplankton. The male guards the eggs in an abandoned tube worm or empty shell. Because of its small size it has no fishery importance, but it is an important prey.
