Opossum shrimps are so-called because they carry their eggs and young in a marsupium-like pouch. The young which hatch from it are miniatures of the adults. The legs are more adapted for swimming than walking and each has two branches. The tail fan has a pair of statocysts, cavities containing a floating particle and acting as a balancing organ in much the way the cochlea does in the human ear.
Shallow water and seagrass beds, to depths of 12 m.
