Felix Lever and her father Ashley were taking part in a bit of rockpooling close to Wembury when they made the rare find: a rainbow sea slug.

The 3cm long sea slug is part of a group of marine animals known as nudibranchs – known for their soft bodies and similarity to land slugs and snails.

Felix and Ashley’s discovery of a rainbow sea slug is believed to be the first time the animal has been recorded in Devon. Only a handful of similar finds have ever been made across the UK with others being concentrated in Cornwall and the Isles of Scilly.
