Where do Phronima live?

Meet Phronima, the pram-pushing, barrel-riding parasite. These tiny creatures are found throughout the world's oceans, except polar regions, swimming in open water. This sets them apart from their relatives, crabs for example, which typically stick to the safe confines of the seabed.

What do Phronima eat?

Phronima is a member of a group of animals called amphipods. They're tiny crustaceans -- relatives of shrimp. Some amphipods creep along the ocean floor, feeding off the organic matter that falls to the bottom. Others float in the water column and eat microscopic plants or animals.
