It’s always great when you find a new species to you. A headshield sea slug, Aglaja tricolorata.

These live on a sandy bottom and borrow into the sand. They grow to 40mm in length and have a very fine “tail” which can be up to twice their body length. Although called a tricolor, they are always brown and spotted white.
