Redclaw crayfish are a moderately large freshwater crayfish. They have a smooth body which is greenish in colour. Redclaw are distinguished from other Cherax species by having 4 carinae (or ridges) on the dorsal surface of the cephalothorax - 2 extending posteriorly from the rostrum and 2 on the postorbital region.


Redclaw live in rivers of northern Australia. Redclaw inhabit permanent fresh water to a depth of 5 metres and are abundant in the headwaters sections of rivers. They can live in a variety of habitats, from shallow, clear, fast flowing creeks to the deep, still and often turbid waters of billabongs. Redclaw prefer sites with abundant aquatic vegetation that provides cover. They leave the water regularly and can exist in stagnant or poor quality waters.
