About

A large anemone found on rocky shores all around the UK and on the seabed down to depths of 100m. They have a stout column ("body") and up to 160 short thick tentacles. Named after dahlia flowers, they come in a wide range of beautiful colours including pinks, purples, yellows and oranges; though they are most commonly a reddish brown. The tentacles are often striped, though they can also be plain. Fragments of sand, shell and gravel stick to grey warts on the body, helping to camouflage them. They feed on small fish and crustaceans, using their stinging tentacles to immobilise passing prey.

What to look for

Distinguished from other anemones by the banded tentacles and the warty 'body' often accessorised with fragments of gravel or shell. Dahlia anemones are very variable in colour, including pinks, purples, yellows, oranges and whites but most commonly a reddish-brown. Their short tentacles are normally banded (striped) but can be plain. They are reasonably large, with those living offshore the largest of all.

Where to find

On rocky shores around all our coasts and offshore to 100m deep.

Dahlia anemones can form dense carpets on the seabed - creating a bit of an underwater garden. Beautiful… but deadly!
