Diagnosis

Oscarellidae without skeleton, with thinly encrusting to lobate shape. Thin ectosome (<100um), often nearly limited to the pinacoderm, true cortex absent. Mesohyl ill-developed, with a proportion of mesohyl to chambers varying from 0.5 : 1 to 1.2 : 1. The aquiferous system has a sylleibid-like organisation, with spherical, eurypylous choanocyte chambers uniformly arranged around large, regular exhalant canals, and a large basal exhalant cavity (after Boury-Esnault et al. 1995).
