Carnivorans live in an unusually broad range of environments. Members of the mammalian order Carnivora occur in tropical forests, temperate woodlands, grasslands, deserts, mountains, tundra, rivers, wetlands, coastlines, Arctic sea ice, and the open ocean. That range includes familiar land mammals such as cats, dogs, bears, raccoons, mongooses, and skunks, as well as semi-aquatic otters … Read more

Carnivoran social behavior spans a much wider range than the familiar image of a wolf pack or lion pride. Some members of the order Carnivora spend most of their adult lives alone, others form long-term pairs or family groups, and some live in packs, prides, clans, cooperative groups, or dense seasonal breeding gatherings. Even within … Read more

Carnivoran senses are not built around one universal superpower. Cats, dogs, bears, mustelids, hyenas, raccoons, seals, and their relatives solve very different sensory problems, so they do not rely on smell, hearing, vision, or touch in exactly the same way. A stalking cat benefits from detecting faint movement in dim light. A canid following a … Read more

Carnivorans communicate through more than howls, roars, growls, and barks. Members of the order Carnivora also exchange information with scent, facial expression, ear and tail position, body posture, touch, and combined signals. A solitary cat scent-marking, a wolf pack howling, a spotted hyena pasting odor onto grass, and a sea lion mother calling to her … Read more

Carnivorans use far more feeding strategies than the familiar image of a big predator chasing prey. Some cats stalk and ambush. Wolves can pursue large prey cooperatively. Bears dig, graze, pick berries, catch fish, and search for insects. Raccoons probe and manipulate objects. Sea otters dive for bottom-dwelling invertebrates. Pinnipeds pursue prey underwater. Giant pandas … Read more

Carnivorans do not all eat the same kind of food. The mammalian order Carnivora includes strongly meat-specialized cats, flexible canids, bears that range from seal-eating polar bears to bamboo-specialized giant pandas, fruit-eating or omnivorous procyonids and viverrids, insect-eating mongooses, fish-catching otters, and marine pinnipeds that feed on many kinds of ocean prey. That diversity is … Read more

Carnassial teeth are the specialized cheek teeth that form the main shearing pair in the ancestral dental pattern of carnivoran mammals. In a typical carnivoran, the upper fourth premolar and lower first molar meet like opposing blades, helping slice tough food as the jaws close. They are not the long canine teeth at the front … Read more

Caniformia is one of the two major living branches of the mammalian order Carnivora. The name literally points toward a “dog-like” branch, but that label can be misleading if taken too literally. Caniforms include dogs and foxes, yet they also include bears, red pandas, raccoons, skunks, weasels, otters, seals, sea lions, and walruses. Some run … Read more

Feliformia is one of the two major living branches of the mammalian order Carnivora. It includes the cat family, but it also includes hyenas, mongooses, Malagasy carnivorans, civets, genets, Asian linsangs, and the African palm civet. That makes Feliformia much broader than the familiar phrase “cat-like carnivorans” can suggest. The members of this branch share … Read more

Feliforms and caniforms are the two major living branches of the mammalian order Carnivora. Feliformia includes cats, hyenas, mongooses, civets, Malagasy carnivorans, Asiatic linsangs, and the African palm civet. Caniformia includes dogs, bears, red pandas, raccoons, skunks, mustelids such as otters and badgers, plus seals, sea lions, and walruses. The names are often translated as … Read more
