Native white-clawed crayfish
The distribution of the white-clawed crayfish (Austropotamobius pallipes) is governed by geology and water quality. The species can be found in a variety of locations including canals, streams, rivers, lakes, reservoirs and water-filled quarries, where it occupies cryptic habitats.
Populations are concentrated in northern and central England. They are largely nocturnal, with breeding taking place from September to November when water temperatures drop below 10°C for an extended period.
