Red hairy hermit crab, Dardanus sp.
Voracious eaters these crabs would eat anything passing by! Hermit crabs have a very vulnerable body compared to crabs thus they need a shell to protect them and keep them safe. When they get bigger they look for a new shell and move into the new house, leaving behind an eerie replica of themselves; a complete shed/moult of their skin, like in the image below:
This is a spider crab, also found in our waters.
