Definition. Chalinidae with an anisotropic, ladder-like choanosomal skeleton consisting of uni- to multispicular primary lines, connected by irregular unispicular secondary lines. Ectosomal skeleton usually absent; if present, consisting only of some vaguely strewn tangentially oriented oxeas. Spongin moderate to absent. Megascleres usually slender oxeas with acerated points. No microscleres (Muricy et al. 2015).
