Paranephrops

Paranephrops is a genus of freshwater crayfish found only in New Zealand. They are known by the English common names freshwater crayfish and koura, the latter from their Māori name of kōura. The two species are the northern koura, Paranephrops planifrons, found mainly in the North Island, but also in Marlborough, Nelson, and the West Coast of the South Island, and the southern koura, Paranephrops zealandicus, found only in the eastern and southern of the South Island and on Stewart Island/Rakiura. Both species are a traditional food for Māori, and a small koura aquaculture industry supplies the restaurant market.
