Cladorhizidae (Gk. “branch” + “root”) are carnivorous sponges. Unlike the others, they don’t feed by gently filtering bacteria and other particles through innumerable pores.

Tiny Asbestoplumae and other carnivorous sponges have hooklike spicules that trap small crustaceans and other passersby, and this is not necessarily a passive process: these species can actively fish (or shrimp) for their prey. Then other kinds of cells grow around the victim and release enzymes that digest it over the course of several days. These carnivores are usually small sponges that live, unsurprisingly, in nutrient-poor waters.
