Phronima sedentaria is a species of amphipod crustacean found in oceans at a depth of up to 1 km (1 mi).

Description
Females are up to 42 millimetres (1.7 in) long, while males are only 15 mm (0.6 in) long.[3]
Distribution
P. sedentaria is found in temperate, subtropical and tropical waters of all the world's oceans, including the Mediterranean Sea.[2] It is usually found in midwater pelagic habitats, but can be found migrating all the way to the surface.
Ecology
Females live in the barrel-like bodies of salps, and use their strong pleopods to propel their homes through the water. The amphipod can somersault quickly in the barrel and thus change directions. Phronima sedentaria is carnivorous on zooplankton, krill, and arrowworms.[4]
