The carnivorous sponge Asbestopluma occidentalis passively prey on tiny crustaceans. When a tiny animal (such as an Artemia sp. bring shrimp) swims into the sponge, they get stuck to the hook-like anisochelae spicules that externally coat the entire sponge. More actively swimming crustaceans, however, like these 24 hrs old Artemia sp. nauplii have the ability to break free from the sponge and swim away.
The individual sponges were placed in petri dishes with Artemia nauplii and time lapsed. Images were taken every 30 seconds and combined into a movie (25 fps, 1080p, h264 codec).
