Truthfully there is not much to be said about canine teeth. The adaptations required to develop a couple of long, sharp, recurved teeth towards the front of the jaw are simple enough. They have occurred countless times from fish to felines. The utility of such a device is fairly obvious. The teeth get plunged into the selected recipient, and any additional force serves to gouge out a pound of flesh like a heated ice cream scoop. Canines almost always occur as a single pair -- or a pair on each jaw -- since having more than that, unless they were perfectly aligned, would require the teeth to cut laterally through the prey to some degree. This is messy, inefficient and unnecessary. ATW001113.
