Jasus edwardsii, the southern rock lobster, red rock lobster, or spiny rock lobster, is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands.
This species is commonly called crayfish or crays in both Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.
