Cherax quadricarinatus

Cherax quadricarinatus, commonly known as the red claw crayfish, is a freshwater crustacean native to Australia and Papua New Guinea. Recognizable by its vibrant red claws and blue-green body, it typically grows up to 15–20 centimeters long. It inhabits rivers, lakes, and streams, where it burrows and forages for plants, insects, and small aquatic animals. Often cultivated for culinary purposes, it’s valued for its tender meat. The species is also popular in aquariums and aquaculture, but care should be taken to prevent its escape into non-native environments, as it can become invasive.
