Ynghylch

The porcelain crab, also known as the broad-clawed porcelain crab, is a small crab covered in tiny hairs. They have large, flattened hairy claws and are brown in colour. They live under rocks and boulders on rocky shores - though they can be hard to spot as their brown hairy bodies are well camouflaged. They are filter feeders, combing plankton from the water using special hairs on their mouthparts.

Porcelain crabs are fragile animals and will shed a leg if attacked, in the same way that a lizard sheds its tail. It's this fragility that gives them their name!

Sut y gall bobl helpu

When rockpooling, be careful to leave everything as you found it - replace any rocks you turn over, put back any crabs or fish and ensure not to scrape anything off its rocky home.
