Ianthella basta, commonly known as elephant ear sponge, is a species of fan-shaped sea sponge in the class Demospongiae. It is also known as the paper sponge or scroll sponge.[2]

Sponges are marine invertebrates with a jellylike mesohyl sandwiched between two layers of cells. They are filter feeders maintaining a flow of water through their structure which passes out through large openings called oscula. They have a fragile skeleton of stiff spicules.

Distribution

The elephant ear sponge is found in the Indo-Pacific region including Indonesia and the Great Barrier Reef.[1] It is found on coral reefs in areas with rapid water flows.[2]

Ecology

The sea cucumber (Synaptula lamperti) is closely associated with the sponge and makes use of certain nutrients exuded by it.[3]

Research is being undertaken on various metabolites and other biologically active constituents that are synthesized by the sponge.[4][5]
