## Quick answer

The sea bunny (Jorunna parva) is a tiny sea slug, a type of nudibranch, that grows to just 1 to 2.5 cm long. It lives on shallow reefs and rocky seabeds across the western Pacific and Indian Oceans, where it crawls slowly over the bottom feeding on sponges. Its fuzzy black-speckled body and two upright rhinophores give it an uncanny resemblance to a miniature rabbit. Most live only about a year.

## What the sea bunny actually is

Despite the cute nickname, the sea bunny is not a mammal but a nudibranch, a shell-less marine snail known as a sea slug. It belongs to the dorid group of nudibranchs and rarely exceeds 2.5 cm in length. The 'ears' that make it look rabbit-like are actually rhinophores, sensory organs it uses to detect chemicals in the water. The 'fur' is a dense covering of tiny bristle-like structures called caryophyllidia scattered across its back.
