Emperor shrimp on nudibranch
Periclimenes imperator
Sighting evidence at Manado Tua Volcano Slope
Emperor shrimp are commensal crustaceans that hitchhike on nudibranchs, sea cucumbers, and Spanish dancers. They feed on the microorganisms disturbed by their host's movement and are small enough — under 2 cm — that they are invisible without deliberate searching. Manado Tua's rubble zones host abundant nudibranch populations that serve as emperor shrimp hosts, making this one of the better sites in North Sulawesi for the combination encounter.
