Hedgehogs have a fairly typical mammalian skeletal structure, but with much longer hind and fore-legs than most people imagine. The skull is broad and blunt with well-developed cheek bones. The jaw can exert a surprising amount of force do to the musculature attachment being located well-forward of the cheek bones.
The cranial cavity is small, but contains a brain that, while primitive in many aspects, is surprisingly more complex than first observations suggest.
Dentition consists of 36 teeth which are highly suited to both an insectivorous and omnivorous diet.
