Carnivores, in the context of the biological order Carnivora, comprise a diverse clade of mostly mammalian predators characterized by specialized dentition, particularly enlarged canines and carnassial teeth adapted for shearing flesh. Members of Carnivora include families such as Felidae, Canidae, Ursidae, Mustelidae, and others, exhibiting a wide range of dietary strategies from obligate carnivory to omnivory. They share morphological and physiological traits such as a generally well-developed sense of smell, often acute vision and hearing, and cranial and limb adaptations for hunting, scavenging, or opportunistic feeding, making the order ecologically pivotal as apex and mesopredators in many terrestrial and some aquatic ecosystems.
Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, ...
