Sponges are an ancient group of animals that diverged from other metazoans over 600 million years ago. Amphimedon queenslandica, is a demosponge from the Great Barrier Reef. It is a useful subject for studying the evolutionary origins of metazoan development, and is the first member of phylum Porifera to have had its genome sequenced (published in 2010).

Like many sponges Amphimedon queenslandica has a biphasic life cycle, residing in different aquatic layers throughout its lifespan. Free-swimming larvae are found in the pelagic zone whereas sessile adults are found in the deeper benthic zone. As a hermaphrodite Amphimedon queenslandica reproduces sexually by releasing sperm into the water which then fertilize eggs that are retained internally.

The genome was sequenced and assembled by the Joint Genome Institute in 2010. The 167 Mb genome assembly was constructed from 9x coverage Sanger shotgun sequencing and covers 97% of the protein-coding regions. There are predicted to be 30,060 protein-coding genes.
