Metacarcinus edwardsii, sometimes known as mola rock crab,[1] southern rock crab,[2] or Chilean rock crab,[2] is a species of crab from the Pacific coast of South America.[1][3]
Distribution
Metacarcinus edwardsii is found along the Pacific coast between Guayaquil in Ecuador and the Beagle Channel in the southernmost Chile.[3]
Description
Females reach functional maturity at carapace width 106 mm (4.2 in), that is, 50% of females are egg-bearing at this size. Males reach functional maturity at slightly larger sizes.[4] The largest male crabs measure about 165 mm (6.5 in) in carapace width.[5]
Metacarcinus edwardsii is univoltine, with the mating season from October to January.[5]
Utilization
In Chile, it is the most important commercially exploited crab, caught exclusively in artisanal fisheries.[3][4]
