The Galician crayfish ( Astacus leptodactylus ), also European crayfish or narrow scissors cancer called, is a großwüchsiger Eastern European crayfish . Like the noble cancer, it is threatened by the cancer plague .
description
The Galician marsh crayfish grows to 16 to 18 cm, in extreme cases up to 25 cm. The basic color is usually light sand-colored to light brown. It is built more slender than the noble crab, the most striking distinguishing feature are the two extremely elongated scissor fingers.
habitat
The crab prefers warm, nutrient-rich waters of the lowlands or rivers with only low currents. It also lives in very muddy waters ( swamp crabs ). If there are suitable embankments, he digs caves himself. It is more resistant to pollution than the noble crab.
Originally, the cancer was native to the Black Sea and Caspian Sea basins. After the cancer plague occurred, it was used in some waters in Central Europe because it was thought that this species was resistant to cancer plague. All current occurrences in Central Europe are based on these restocking measures.
