Edible Crab

iNaturalist · CC0

Large edible crabs, sometimes over 20 cm across the carapace, are abundant under boulders and within the old fortification stonework at Munkholmen. They are nocturnal foragers and by day sit motionless in crevices, their brick-red shells matching the encrusted rock. The protected status of the broader fjord area means individuals here grow to exceptional sizes rarely seen in fished waters.
