Chondrocladia lyra, also known as the harp sponge, is a species of carnivorous deep-sea sponge first discovered off the Californian coast living at depths of 10,800–11,500 feet (3,300–3,500 m) by scientists from the Monterey Bay Aquarium Research Institute (MBARI). Two specimens have been collected and ten more were filmed. The first specimens seen had two vanes, but specimens with as many as six have been seen since.
