A new species of carnivorous sponge has been discovered off the coast of Canada. Sponges are usually filter feeding animals, with pores which bring water in and a central cavity forcing it back out. This sponge, belonging to the genus Cladorhiza, possesses spine like appendages used to capture zooplankton such as small crustaceans. The sponge was found nearby hydrothermal vents 1.8 miles below the surface.
