}} In taxonomy, the Dendroceratida are an order of sponges of the class Demospongiae.[1] They are typically found in shallow coastal and tidal areas of most coasts around the world. They are generally characterized by concentric layers of fibers containing spongin (a collagen-like material), and by large flagellated chambers that open directly into the exhalant canals. Along with the Dictyoceratida, it is one of the two orders of demosponges that make up the keratose or "horny" sponges, in which a mineral skeleton is minimal or absent and a skeleton of organic spongin-containing fibers is present instead.[2] References1. ^{{cite book | last = Hooper | first = JNA |author2=van Soest RWM | year = 2002 |chapter= Ordo Dendroceratida Minchin, 1900|title = Systema Porifera: A Guide to the Classification of Sponges.
