The white-clawed crayfish (Austropotamobius pallipes) is a freshwater crustacean native to Europe. It is easily recognized by its pale claws, which contrast with its darker body. This species typically inhabits clean, well-oxygenated rivers and streams, where it plays a vital role in the ecosystem by helping to recycle nutrients. These crayfish are primarily nocturnal and feed on a variety of organic materials, including plants and detritus. Unfortunately, the white-clawed crayfish faces threats from habitat loss, pollution, and competition from invasive species like the signal crayfish. Conservation efforts are underway to protect their populations and habitats.
