Crambe crambe, commonly known as the oyster sponge or orange-red encrusting sponge, is a species of demosponges belonging to the family Crambeidae. ^{[1] [2]}

The colonies of Crambe crambe form thin orange to orange-red plates, rarely lobed, with a very rough surface perforated by raised oscula found along the exhaling channels. These colonies can cover a surface of 1 m². ^{[3] [4]}

Crambe crambe feeds by filtering bacteria, microorganisms and single-celled algae. This species is hermaphrodite. Larvae are planktonic. These demosponges often cover the shell of live shellfish ( Arca noae, Spondylus and various sedentary bivalves). Eupolymnia nebulosa sometimes hides itself on these sponges. ^[3]

This species is endemic to the Mediterranean, but it is also present in the North Atlantic Ocean, in the English Channel and in the North Sea. ^{[3] [5] [6]}

Crambe crambe commonly occurs in well-lit waters on hard substrate at depths of 5 to 30 m. ^[3]
