Scienceshot: Carnivorous Candelabra of the Deep With its vertical branches sticking up from the seafloor like a deep-sea candelabra, the harp sponge (Chondrocladia lyra) seems like something out of a Dr. Seuss book. But the newly described invertebrate isn&amp;#8217;t so benign. Rather than filtering the water for bacteria and other single-celled organisms like most sponges do, the harp sponge employs Velcro-like barbs on its vertical branches to snag tiny crustaceans called copepods as they swim past.
