Noble Crayfish

Also known as European Crayfish, Broad-fingered Crayfish

Noble crayfish inhabit clean, oxygen-rich rivers and lakes across Europe, digging shallow burrows along muddy banks or sheltering beneath submerged stones. Active primarily at night, they forage on detritus, water plants, and small invertebrates while playing a vital role in aquatic nutrient cycling. Severe declines have occurred over the past century due to habitat degradation and the introduced fungal crayfish plague.
