}}Metacarcinus edwardsii, sometimes known as mola rock crab,[1] southern rock crab, or Chilean rock crab, is a species of crab from the Pacific coast of South America.[1][5] DistributionMetacarcinus edwardsii is found along the Pacific coast between Guayaquil in Ecuador and the Beagle Channel in the southernmost Chile.[5]DescriptionFemales reach functional maturity at carapace width {{convert|106|mm|abbr=on}}, that is, 50% of females are egg-bearing at this size. Males reach functional maturity at slightly larger sizes.[7] The largest male crabs measure about {{convert|165|mm|abbr=on}} in carapace width.[8] Metacarcinus edwardsii is univoltine, with the mating season from October to January.[8]UtilizationIn Chile, it is the most important commercially exploited crab, caught exclusively in artisanal fisheries.[5][7] References1. ^1 2 {{cite journal|last1=Pardo|first1=Luis Miguel|last2=Fuentes|first2=Juan Pablo|last3=Olguín|first3=Andrés|last4=Orensanz|first4=J.
