The Emperor shrimp, (Periclimenes imperator), is a species of shrimp with a wide distribution across the Indo-Pacific. It lives commensally on a number of hosts, including the sea slug, Hexabranchus. A. J. Bruce first described it in 1967 based on eight specimens ranging from 4 millimetres (0.16 in) to 7.6 millimetres (0.30 in), and found Periclimenes rex to be its best resemblance.
