This half crab is another introduce invasive species that can be found around Tasmania in ever expanding ranges. Locally this crab is just about everywhere you can lift up a rock along Tomahawk Beach and around Tomahawk Island.
This crab often drops legs as an escape mechanism regrowing them over time like how lizards drop their tails.
This is an invasive species within Tasmania and as such it is an offence to use these crabs as bait or to move them around despite the fact, they are now readily established state-wide.
