Amphimedon queenslandica is a marine demosponge from the Great Barrier Reef. It was first discovered in 1998 and was formally described in 2006. It is a hermaphroditic species whose eggs are fertilised internally by sperm spawned into the ocean. Amphimedon queenslandica has a larval and a benthic stage. This sponge was the first member of phylum Porifera to have its genome sequenced. Analysis of this genome has contributed to our understanding of the evolution of animal complexity.

Amphimedon queenslandica (formerly known as Reniera sp.) is a sponge native to the Great Barrier Reef. Its genome has been sequenced. It has been the subject of various studies on the evolution of metazoan development.
A. queenslandica was first discovered in 1998 on Heron Island Reef by Sally Leys during a survey of sponge species, and was formally described by John Hooper and Rob van Soest in 2006. Like most sponges, it has a biphasic life cycle, passing through a planktonic phase whilst a larva, but later becoming a benthic dweller. It is hermaphroditic, and reproduces via spermcast spawning, meaning it releases sperm into water but retains eggs, which are fertilised internally. The embryos develop in brood chambers until they reach a certain size, then disperse as parenchymella larvae. During this larval stage, they have a strong preference for darkness. The sponge is difficult or impossible to maintain in captivity.
