This species of swimming crab is more common on the coasts of New Zealand but is also reported from south-eastern Australia. Spending much of their time burrowed into sandy or muddy sediments paddle crabs are efficient swimmers, using the flattened last pair of legs as paddles. These swimming legs and the pointed toothed and spined claws enable them to be highly active and aggressive predators.
Intertidal to 50 metres depth.
West Pacific Ocean (New Zealand and Chatham Islands), including south-eastern Australia.
Not harmful but a nip from large claws could be painful
