Amphimedon queenslandica (formerly known as Reniera sp.[1][2]) is a sponge native to the Great Barrier Reef. Its genome has been sequenced.[3] It has been the subject of various studies on the evolution of metazoan development.[1][4]
A. queenslandica was first discovered in 1998 on Heron Island Reef by Sally Leys when looking for sponges with larvae to study polarity,[5] and was formally described by John Hooper and Rob van Soest in 2006.[6] Like most sponges it has a biphasic life cycle, passing through a planktonic phase whilst a larva, but later becoming a benthic dweller.[5] It is hermaphroditic, and reproduces via spermcast spawning,[3] meaning it releases sperm into water but retains eggs, which are fertilised internally.[7] The embryos develop in brood chambers until they reach a certain size, then disperse as parenchymella larvae.[5][8] During this larval stage, they have a strong preference for darkness.[5][9][2] The sponge is difficult or impossible to maintain in captivity.[5]
Genetics
The genome of Amphimedon queenslandica was sequenced in 2009 to provide insights into the evolution of animal complexity[3] and was the first sponge to be sequenced. Subsequent research has also sequenced the genome of the freshwater sponge Ephydatia muelleri.[10]
