Does not move

The Danube crayfish often hides during the day at the bottom where it is well-hidden between rocks and plants. During the night, it uses its antennae to find food and uses its claws to hold onto the food.

Get to know a crayfish

There are 3 species of freshwater crayfish in Denmark. All live at the bottom of lakes and streams. The Danube crayfish has the longest claws and antennae, and the colour of its shell is more greenish.

Not a native species

The crayfish originally comes from Turkey. It was released in Denmark in order to be caught and eaten by humans.

Drives out the Danish European crayfish

The Danube crayfish is better at handling cold and pollution than the indigenous European crayfish. It therefore takes over the habitat of the European crayfish and is a problem for Danish nature.
