During Dive 11 of Windows to the Deep 2021, on a limestone scarp in the Florida Straits, we saw two different kinds of carnivorous sponges, including this huge Chondrocladia sp. at a depth of 1,139 meters (3,737 feet). Unlike typical sponges that feed by pumping water through their bodies and filtering out tiny suspended particles (like bacteria), carnivorous sponges use Velcro-like structures on their branches to capture prey. Carnivorous sponges favor larvae and small crustaceans, which once caught, they engulf and digest.
