Phronima is a genus of small, deep sea hyperiid amphipods of the family Phronimidae. It is found throughout the world's oceans, except in polar regions.[1] Phronima species live in the pelagic zone of the deep ocean. Their bodies are semitransparent. Although commonly known as parasites, they are more technically correctly called parasitoids.[2] Instead of constantly feeding on a live host, females attack salps, using their mouths and claws to eat the animal and hollow out its gelatinous shell.[3] Phronima females then enter the barrel and lay their eggs inside, and then propels the barrel through the water as the larvae develop, providing them with fresh food and water.[3]
