The order Carnivora includes a great deal of diversity. There are 15 families and about 268 species. Almost all of these species eat meat instead of the easier to obtain vegetable matter. Because of this, carnivorans are considered one of the major groups of mammalian predators. They occur naturally on all continents except Australia (the dingo was introduced some 4,000 years ago).
While most carnivorans are meat eaters, this is not a characteristic of this order. Instead, living carnivorans share morphological characteristics such as specialized teeth. Using morphology to group like organisms in this order, morphology is also used to split the order into two major suborders. The Suborder Feliformia and the Suborder Caniformia are split based on the structure of the auditory bullae and their carotid circulation.
