The Boneshark is a large shark-like creature plated with a thick, hard segmented exoskeleton, featuring a large head and irregular teeth that, instead of protruding from the gums, are an extension of its exoskeleton. Though it lacks dorsal fins, it does have two barbed pectoral fins and a set of bony flukes. It is grey in color with orange patterns on its head and on the peripherals of each bone plate. The shark also features two reflective green eyes with slit, snake-like pupils.
