Taxonomy The order Keratosa was used prior to Lévi's (1955) rearrangement of the Demosponge orders to accomodate sponges lacking spicules and provided with spongin fibers. This is now considered an artificial group because the orders Verongiida, Dictyoceratida, Dendroceratida and family Halisarcidae were included in the concept of Keratosa. From multidisplinary studies involving biology, chemistry, microbiology and genetics it is demonstrated that Verongiida and Halisarcidae are unrelated to Dictyoceratida and Dendroceratida. Recent molecular studies favour the use of the name Keratosa for a subclass consisting of the orders Dendroceratida and Dictyoceratida only (Erpenbeck et al. 2012) and the former order Verticillitida.

Taxonomy The order Keratosa was used prior to Lévi's (1955) rearrangement of the Demosponge orders to accomodate sponges lacking spicules and provided with spongin fibers. This is now considered an artificial group because the orders Verongiida, Dictyoceratida, Dendroceratida and family Halisarcidae were included in the concept of Keratosa. From multidisplinary studies involving biology, chemistry, microbiology and genetics it is demonstrated that Verongiida and Halisarcidae are unrelated to Dictyoceratida and Dendroceratida.
