The hairy stone crab (Lomis hirta) is a special type of crab-like creature. It is a crustacean, which means it's related to crabs, lobsters, and shrimp. This interesting animal lives along the southern coast of Australia. It is the only species in its entire family, making it quite unique!

Discovering the Hairy Stone Crab
The hairy stone crab was first described in 1818. This means scientists officially named and recorded it then. It was named by a famous scientist called Jean-Baptiste de Lamarck.
What the Hairy Stone Crab Looks Like
This small crab is usually about 1.5 to 2.5 centimeters (about 0.6 to 1 inch) wide. That's roughly the size of your thumb! It moves quite slowly. The crab is covered in brown hair. This hair helps it to camouflage itself. Camouflage means it blends in perfectly with the rocks where it lives. This makes it very hard for predators to spot it.
Where the Hairy Stone Crab Lives
The hairy stone crab lives in the littoral zone of southern Australia. The littoral zone is the part of the ocean that is close to the shore. It is the area between the high tide and low tide marks. This means it can be covered by water at high tide and exposed to air at low tide. You can find these crabs from Bunbury, Western Australia, all the way to the Bass Strait. The Bass Strait is the sea channel that separates mainland Australia from the island of Tasmania.
Its Place in the Animal Family Tree
Scientists study how different animals are related. The hairy stone crab is part of a group called Anomura. This group includes animals like hermit crabs and king crabs. For a long time, scientists have debated exactly how Lomis hirta fits into this group. It is clear, however, that the hairy stone crab is a special case. It developed its crab-like shape independently from other true crabs. This process is called carcinisation. It shows how different animals can evolve similar body shapes over time.
