Distribution edit
Metacarcinus edwardsii is found along the Pacific coast between Guayaquil in Ecuador and the Beagle Channel in the southernmost Chile.[3]
Description edit
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 edit
In Chile, it is the most important commercially exploited crab, caught exclusively in artisanal fisheries.[3][4]
