From: The ontogeny of choanocyte chambers during metamorphosis in the demosponge Amphimedon queenslandica
Proposed model of choanocyte chamber formation in A. queenslandica. During metamorphosis, postlarval archeocytes form choanocyte chambers from either a single progenitor cell or multiple cells. Choanocyte chambers grow by proliferation of choanocytes within the chamber and by recruitment of choanocytes into mature chambers
