Ischia Flabelline

In Dive.Explo360: Mediterranean · Northeast Atlantic · Atlantic Ocean

On a hydroid colony, the Ischia Flabelline reveals an elegant outline in shades of pink and purple. Its slender, colourful cerata sway in the current. This little sea slug turns its prey’s weapons into protection, a fascinating behaviour to observe while diving.

WHAT DOES IT LOOK LIKE?

This small nudibranch has an elongated, translucent body, often tinged with purplish pink. Slender dorsal projections called cerata are arranged in rows, giving the animal a finely divided outline. The tips of the cerata are brightly coloured, contrasting with the rest of the body. The head bears two clearly visible, smooth rhinophores. Like other nudibranchs, it has no shell as an adult.

WHERE DOES IT LIVE?

It occurs in the Mediterranean Sea, mainly on rocky seabeds rich in hydroids. It is found on walls, in coralligenous areas and on substrates where its prey are abundant, generally between a few metres and around forty metres deep.

WHAT DOES IT EAT?

It feeds almost exclusively on hydroids. Using its radula, it captures and consumes these small attached organisms. It can take the stinging cells from its prey and store them in its own tissues for defence.
