Slipper Limpet

Crepidula fornicata

About

The Slipper Limpet normally lives in stacks of individuals, with the largest at the bottom and increasingly smaller animals on each other's backs, out beyond the low tide mark. Accidentally introduced from North America, and now a serious pest of oyster and mussel beds.

How to identify

Unmistakeable, slipper-shaped, oval shell. Normally pale creamy in colour with blotches of orangey-red.

Where to find it

Found around the coasts of East Anglia, the south of England and South Wales.

How can people help

The human-induced invasion of non-native species on our shores can be detrimental for many of our native species as they compete for space, food and become prey. Our seas and coastline are in need of protection if we are to keep our marine wildlife healthy. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives. This work has recently had a massive boost with the passing of the Marine Bill, promising sustainable development of the UK's marine environment. Do your bit for our Living Seas by supporting your local Wildlife Trust.
