Thin Tellin

Angulus tenuis

  1. Wildlife
  2. Bivalves
  3. Thin Tellin


A small clam-like shell, the Thin Tellin is oval, smooth and delicate. It is found in fine sand from the middle of the shore to the sea, and buries itself up to 12 cm deep. It is a filter feeder, extracting organic matter from the water using its long siphon which it extends to the surface of the sand. Sometimes the siphon tip gets nibbled by a passing flatfish, but the Thin Tellin does not die - it just grows a new one.

How to identify

An easily recognised seashell, the Thin Tellin is very pretty, coming in various shades of pink and yellow.

Where to find it

Found on fine sandy shores all round our coasts.

How can people help

Molluscs provide a vital link in the food chain for many of our rarer species. 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.
