The dog's tongue ( Glyptocephalus cynoglossus ), also known as eel , is a right-eyed flatfish of the North Atlantic from the plaice family (Pleuronectidae), not the dog's tongue (Cynoglossidae). The name red tongue is also used for the Limande ( Microstomus kitt ).

description

The slim (3 to 4 times as long as high) flatfish with a small head compared to plaice and flounder grows up to 50 cm long. The sideline is complete and, in contrast to the dab , but just like the Limande, is straight. The pectoral fin on the side of the eye, with a blackish border, is shorter than the head. There are large pores of mucus on the blind side of the head. The dog's tongue is monochrome gray to reddish brown and has rough scales.

Distribution and way of life

The dog's tongue occurs in the temperate latitudes on both sides of the North Atlantic , on the European coast (including the North Sea ) from northern Spain to and including Norway, on the North American coast from the Gulf of Saint Lawrence to North Carolina .

It inhabits muddy bottoms in 18 to 1,570 meters deep and feeds there from crustaceans , bristle worms , brittle stars and fish. It reproduces slowly: it takes 4½ to 14 years to double the population.

Use and endangerment

The dog's tongue is hardly known in Germany; where it is better known, however, it is a valued and expensive food fish . Because of its relatively slow reproduction, it is considered to be sensitive to overfishing .
