The brain sponge (Isodictya elastica) is a species of marine demosponge in the family Isodictyidae.[1] This sponge is known from the west coast of South Africa to Port Elizabeth. It is endemic to this region.[2]
The brain sponge may grow to 20 centimetres (7.9 in) across. It has a smooth surface, covered with many scattered oscula. It may be beige to pink in colour and grows in two forms: one massive and convoluted, rather like a brain, and the other with narrowing fingers. Its texture is soft and compressible.[2][3]
This sponge lives on rocky reefs subtidally to 25 metres (82 ft).
