The brain sponge (Isodictya elastica) is a species of marine demosponge in the family Isodictyidae. It is present from the west coast of South Africa to Port Elizabeth. It is endemic to this region.

Description

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.

Habitat

This sponge lives on rocky reefs subtidally to 25 metres (82 ft).
