Violet sea slug

Despite its dazzling colouration, this fabulous nudibranch can be easily missed, due to its small size!

Top facts

Up to 5cm long.

Common.

April – October.

Eggs are laid as a thin, white thread and can sometimes be easier to spot than the sea slug itself!

A very small nudibranch with striking violet/pinky-purple colouration, with white tips to the projections running along its back.

Found around all British coasts.

All nudibranchs are sea slugs, but not all sea slugs are nudibranchs!
