Crater Sponge

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

Divers often spot the Crater Sponge by its pinkish shades and surface dotted with characteristic little craters. Living on well-lit rocky walls, it tirelessly filters water and generally indicates a marine environment of good quality.

WHAT DOES IT LOOK LIKE?

This sponge forms patches or cushions lying against the substrate. Its pink to pinkish-orange surface is marked by numerous circular depressions resembling small craters. These structures, with slightly paler rims, give it a characteristic appearance. Its texture is flexible and soft to the touch.

WHERE DOES IT LIVE?

It grows on well-lit rocky substrates, often in areas containing little sediment. It is frequently found on walls, boulders or in coralligenous areas, in clear, well-flushed water.

WHAT DOES IT EAT?

Like all sponges, it feeds by filtering water. Microscopic particles, such as bacteria and organic debris, are captured as water passes through its tissues, then water is expelled through wider openings. This functioning contributes to recycling matter in the marine environment.
