Apolemia

Siphonophores like Apolemia are deep-sea predators—lying in wait for unfortunate animals to blunder into their curtain of stinging cells. Their diet can include tiny crustaceans such as copepods, fish, and even other siphonophores. Although many siphonophores eat whatever they can catch, others are specialists. Some use lures to attract specific prey. Others deploy their tentacles in elaborate feeding shapes, like coils or J-postures. These feeding shapes must constantly be re-set as the animal sinks through the water.
