We don't often think of the open water as "habitat" but many species live all or part of their life in the open water. Planktonic jellyfish Medusae drift in the water column and move short distances by contracting the muscles within the bell-like structure, creating quick pulse-like movements. The tentacles contain harpoon-like stinging cells to capture small planktonic shrimp and crabs. (photo: Shane Anderson)
