Mediterranean triton

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

On a rocky wall or coralligenous seabed, the Mediterranean triton immediately attracts attention through its remarkable size. This large Mediterranean sea snail moves slowly but plays an essential role in limiting certain sea urchin populations. Always an exceptional sighting.

WHAT DOES IT LOOK LIKE?

The Mediterranean triton is the largest shelled mollusc in the Mediterranean, reaching about forty centimetres. Its thick spiral shell is often colonised by algae or other organisms. The opening is closed by a solid operculum. Its body is fleshy, with a powerful orange foot. Two tentacles bear eyes at their base, allowing it to perceive its surroundings while remaining partly sheltered.

WHERE DOES IT LIVE?

It frequents rocky seabeds, coralligenous areas and soft bottoms near hard structures. It is found from a few metres down to great depths, where it moves slowly along the bottom.

WHAT DOES IT EAT?

It is a predator mainly consuming echinoderms such as starfish and sea urchins. It uses its radula, a kind of rasp, together with chemical secretions to attack prey protected by a hard skeleton.
