Yellow Tube Sponge

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

On a drop-off or in a coralligenous area, the Yellow Tube Sponge immediately catches the eye with its bright yellow shades. Its thick, irregular forms contain an extensive filtration system. A feature well known to divers: it quickly darkens when handled or exposed to air.

WHAT DOES IT LOOK LIKE?

This sponge forms upright lobes or tubes joined to varying degrees at the base. Its colour ranges from bright yellow to orange underwater. Each tip has an osculum, an opening through which water is expelled after filtration. Its surface is slightly uneven and its consistency is flexible but firm. When exposed to air or handled, its colour can quickly darken through oxidation of natural compounds.

WHERE DOES IT LIVE?

It mainly occurs in the Mediterranean Sea on rocky substrates. It is found in coralligenous habitats, on walls, overhangs and in shaded areas, from a few metres to several tens of metres deep. It favours well-oxygenated environments, often exposed to moderate currents.

WHAT DOES IT EAT?

It feeds by filtration. Water enters its body through numerous pores, circulates through an internal network and leaves through the oscula. This flow captures very fine particles such as bacteria and suspended organic matter. This feeding method contributes to recycling materials in the water.
