Crabclopses are Lesser Cyclopses relegated to the rocky coasts of various desolate islands by their kin for some ancient transgression that none of them will talk about willingly. They hunt Giant and Gargantuan Crabs as well as Crabmen, feasting upon their flesh and crafting their distinctive armor from their chitinous outer shells.
