Metacarcinus gracilis (Dana, 1852)
The slender crab carapace is usually olive brown, and its legs vary from yellowish brown to purple.
Larvae and small juveniles of this species are often seen riding jellyfish, especially Phacellophora camtschatica. The juvenile crabs steal food from the jellyfish and also clean off parasitic amphipods
Similar to Metacarcinus magister.
