Narrow-Clawed Crayfish

Distribution: Europe, Eastern Russia and the Middle East. Size: 15 cm Eggs per season: 200–400 Maturity: 3 years Diet: Omnivorous IUCN red list status: Least Concern The narrow-clawed crayfish, also known as the Turkish crayfish, varies in color from pale to dark green, yellow, and occasionally blue. It is easily recognized by its long, narrow claws and the rough texture on the upper surface of its claws. Typically, it grows to about 15 cm in length, though some individuals may reach up to 30 cm. This species is omnivorous, feeding on macrophytes and invertebrates. It is active during the day and especially during winter. Spawning occurs in spring, with females laying between 200 and 400 eggs. Narrow-clawed crayfish reach maturity at around three years of age. The species faces several threats, the primary one being overfishing, as it is extensively harvested for food in some countries. It is also vulnerable to pollution and susceptible to crayfish plague, although some individuals possess immunity, allowing populations to recover. The IUCN currently lists it as a species of Least Concern.
