hadromerida
An order of sponges of the class Demospongiae with monactinal megascleres that usually have a terminal knob at one end. Microscleres in the form of streptasters, asters, sigmas, or small spined diactinals may occur. Megascleres tend to be arranged in tracts radiating from the center of the sponge; spongin is usually sparse in occurrence.
