Carnivorous Sponges: The Venus Flytraps Of The Sea

Carnivorous sponges typically live in the deep sea. Unlike other sponges, they aren't filter-feeders, and instead feed on the unfortunate crustaceans that become caught on their velcro-like hooks. The sponges don't have a stomach or digestive system, so they slowly eat their prey at the cellular level: individual cells travel to, cover, and digest their catches. There are more than 100 species of carnivorous sponge known to science.
