Crystalline Sea Squirt

In Dive.Explo360: Mediterranean

Beneath a rock or in a dimly lit crack, the crystalline sea squirt sometimes reveals its pearly shine. This thin, translucent colony, arranged in elongated networks, continuously filters water and contributes to the recycling of organic matter in the marine environment.

WHAT DOES IT LOOK LIKE?

The crystalline sea squirt is a colonial sea squirt that forms thin, translucent patches attached to a surface.The small individuals making up the colony are arranged in rows or elongated networks, rather than rosettes as in some related species.Its colour is generally very pale, from whitish to lightly tinted, with an often shiny appearance that gives it a pearly effect.

WHERE DOES IT LIVE?

This species lives attached to hard surfaces such as rocks, shells or other marine organisms.It is mainly found in dimly lit areas: beneath overhangs, in hollows or cavities, often where currents bring particle-rich water.It can be seen from shallow water down to several tens of metres.

WHAT DOES IT EAT?

The crystalline sea squirt feeds by filtering seawater.Each individual draws in water and retains microscopic particles such as phytoplankton and suspended organic matter.The filtered water is then released through openings shared by several individuals in the colony.
