Hairy Stone Crab

About

Not considered a true crab as it only has the three walking legs besides the claws, this species is easy to identify due to its shape and features.

The shape and features of this crab allow it to blend in well although hinder its ability to move making slow and hard for them to turn back over if they get on their back.

Locally this crab can be found around the Island and around the rocks from Tomahawk Point through to West Tomahawk Beach

Size

Can grow to around 30mm across the carapace

Habitat

Can be found under rocks at intertidal levels on exposed rocky coasts

Distribution

Southern Australia including around Tasmania.
Locally they can be found around the island and along the rocks towards West Beach

How to Identify

A small triangular shaped crab covered in short setae with only three walking legs

The crab's small hairs, or setae, capture silt and sand, enhancing its camouflage in its habitat. It features a flat, triangular carapace and with only three legs that fit snugly against its body and each other. Its claws (chelae) are large and flattened. While the crab typically blends in well, its bright blue antennae become visible when the claws are spread apart.
