Feeding
Most carnivores live on a diet of freshly killed animal
prey, ranging in size from insects, other invertebrates,
and small vertebrates to animals as large as buffaloes
and reindeer. Carnivores are generally adaptable
feeders, seldom restricting themselves to a single
food type. However, there are specialists—for
example, there are pinniped species that eat only
fish. Others, such as bears, badgers, and foxes, eat
a mixed diet of meat and plants, while a few, notably
the giant panda, are almost entirely herbivorous.

Establishing and maintaining bonds between pack
members is essential for the survival of dogs that
live in social groups. In African wild dogs, bonding
behavior, such as licking and whining, frequently
occurs before a hunt. It is only by cooperating and
hunting as a team that the dogs are able to bring
down and kill prey larger than themselves.

large deer or musk oxen.

PHYSICAL INTIMIDATION
Bears can be aggressive animals, particularly when
competing with each other during the breeding season.
When male brown bears come into conflict, they will
often try to intimidate one another by making themselves
look as large as possible, growling and displaying their
teeth. Smaller individuals will usually give way to
larger ones, but if a warning is ignored, actual fighting
will break out, often leading to serious injury or death.
