Amphimedon queenslandica (formerly known as Reniera sp.
A. queenslandica was first discovered in 1998 on
benthic dweller.[6] It is hermaphroditic, and reproduces via spermcast spawning,[4] 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.[6][8] During this larval stage, they have a strong preference for darkness.[6][9][3] The sponge is difficult or impossible to maintain in captivity.[6]
Genetics
The genome of Amphimedon queenslandica was sequenced in 2009 to provide insights into the evolution of animal complexity[4] and was the first sponge to be sequenced. Subsequent research has also sequenced the genome of the freshwater sponge Ephydatia muelleri.[10]
