These small, highly attractive sea snails are very common across most seashores and shallow waters, spending most of their time grazing on seaweed and rocks. Occasionally, you can see their two striped antennae sticking out when they are on the move.
How to identify
The flattish shell usually consists of alternating green/grey and purple bands, which tend to fade as the snail gets older. Gently turn the shell over and look for a small hole on the underside, along with the characteristic ‘mother of pearl,’ which all topshells possess.
Did you know?
This topshell’s scientific name ‘umbilicalis’ comes from the large hole on its underside, like a belly button!
How people can help
Always follow the Seashore Code when rockpooling, taking care where you walk and making sure you put animals and rocks back gently.
