Snake-locks Anemone

Anemonia sulcata


Sea anemones live attached to the rocks, catching plankton and tiny animals from the water with their stinging tentacles. They can be found in rock pools around the low tide mark, sometimes in small groups. The Snake-locks Anemone has a squat, jelly-like 'body' with long, wavy, snake-like tentacles which cannot be retracted.

How to identify

How can people help

Sea anemones may be a familiar sight when rock-pooling, but 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.
