Mycale laevis, the orange icing sponge or orange undercoat sponge, is a species of marine demosponge in the family Mycalidae. Mycale is a large genus and this species is placed in the subgenus Mycale making its full name, Mycale (Mycale) laevis.[1] This sponge is found in the Caribbean Sea and the Gulf of Mexico and usually grows in association with one of a small number of species of coral.

Description

Mycale laevis is yellow, mid to dark orange or yellowish-green. It has a small number of oscules, each up to 4 millimetres (0.16 in) in diameter. They are elevated with a thick white or translucent collar. This sponge is easily torn and its consistency is compressible but firm.[2][3]

Ecology

Mycale laevis usually grows on the undersurface of certain species of corals that form flat plates. These include

parasitic boring sponge. Observation over several years has shown that this is a stable relationship. In the absence of suitable coral species, Mycale laevis is able to live directly on rocks and under boulders as an encrusting or massive sponge[4] and also on calcareous worm tubes.[3]

Distribution

Mycale laevis is found on reefs and in lagoons in the Caribbean Sea, the Gulf of Mexico, the West Indies, the Bahamas and Florida at depths between 1 and 80 metres (3.3 and 262.5 ft) but is more common at depths greater than 25 metres (82 ft).[4]
