Sea Strawberry

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

On a rocky drop-off or within a coralligenous habitat, the Sea Strawberry catches the eye with its pink to bright red shades. It looks like a small fruit resting on the rock. This colony continuously filters water and contributes to the balance of underwater life.

WHAT DOES IT LOOK LIKE?

This colonial sea squirt forms compact pink to reddish clusters pierced by many small openings visible on the surface. A colony may resemble a more or less hemispherical cushion a few centimetres in diameter. Each opening belongs to a microscopic individual incorporated into the colony. The outer tunic consists of tunicin, a cellulose-like substance characteristic of tunicates and rare in the animal kingdom.

WHERE DOES IT LIVE?

It grows on hard substrates such as rocks, algae or coralligenous formations. It occurs in well-oxygenated areas, often exposed to moderate currents that help supply food particles. It is common from shallow water down to several tens of metres deep.

WHAT DOES IT EAT?

It is a filter feeder. Each individual in the colony draws water in through an inhalant siphon, extracts microscopic food particles and then releases the filtered water through an exhalant siphon. Its diet relies mainly on plankton and suspended organic particles.
