Carnivore

A carnivore (KAR-nih-vohr) meaning "meat eater" ( Latin carn = flesh + vorare = to devour) is an animal that eats a diet consisting solely of meat, whether it comes from live animals or dead ( scavenging).

The word also refers to the mammals of the Order Carnivora, many (but not all) of which fit the first definition. Bears are an example of members of Carnivora that are not true carnivores. Carnivores that eat primarily (or only) insects are called insectivores.

Animals that are obligate carnivores

The lion is a well known truly carnivorous member of the order Carnivora.

An obligate or true carnivore is an animal that subsists on a diet consisting only of meat. They may consume other products presented to them, especially animal products like cheese and bone marrow, or sweet sugary substances like honey and syrup, but, as these products are not essential, they do not need to consume these on a regular basis. True carnivores lack the physiology required for the efficient digestion of vegetable matter, and in fact some carnivorous mammals eat vegetation specifically as an emetic.

Domesticated carnivores are often recommended to have vegetable supplements (or such containing processed pet foods) as meats designed for human consumption may be lacking in vital nutrients.

• Felines, ranging from domestic cats to lions, tigers, and other large predators.
• Some canines, such the Grey wolf but not the Red wolf or coyote. Domestic dogs are broadly considered carnivorous but the classification is often debated.
• Hyenas
• Some mustelids, including ferrets
• Polar Bears
• Pinnipeds ( seals, sea lions, walruses, etc.)
• Birds of prey, including hawks, eagles, falcons and owls
• Scavenger birds, like vultures
• Several species of waterfowl including gulls, penguins, pelicans, storks, and herons
  

  In contrast to the lion, these Emperor penguins show that teeth and claws aren't necessary to be a carnivore. They feed on crustaceans, fish, squid, and other small marine life.
• Anurans (frogs and toads)
• Snakes
• Some lizards
• Crocodilians
• Sharks and many other species of fish
• Toothed whales
• Octopuses and squid
• Spiders and scorpions
• Mantophasmatodea, Reduviidae and other insects
• Cnidarians

There are also several species of carnivorous plants. Though most are primarily insectivorous, some digest nematodes and other small invertebrates.

Many dinosaurs were obligate carnivores, namely most –if not all– theropods, like Tyrannosaurus rex. Sauropods and ornithischians were herbivorous.

The root of the word sarcophagus similarly means "eater of flesh", though the meaning is different.
