Taxonomy Prior to Lévi's (1955) rearrangement of the Demosponge orders the name Keratosa was used to accommodate 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. They are here included with Chondrosiida and Chondrillida in the subclass Verongimorpha. The remaining Dictyo- and Dendroceratida are retained in the subclass Keratosa (q.v.). [details]
