A 'social animal' is a loosely defined term for an
organism that is highly
interactive with other members of its
species to the point of having a recognizable and distinct
society.

Gorillas and other higher primates are noted as having similarly complex social structures.
All animals are social to some extent—
sexual reproduction requires animals to come in contact together in order to
mate, and in animals showing any degree of parental care there is a minimal social unit of one or more parents and their offspring. The term "social animal" is usually only applied when there is a level of
social organization that goes beyond this, with permanent groups of adults living together, and relationships between individuals that endure from one encounter to another.
Animal social behaviour and organisation is studied in
comparative psychology,
ethology,
sociobiology,
behavioural ecology and
computer science (
artificial intelligence). Typical issues in social behaviour are:
★ What is the typical size of the group? What factors limit group size? What factors lead to groups merging or splitting?
★ Does the species show
territoriality? If so, to what extent? If territories are maintained, what is their purpose? Are they held by an individual or a group?
★ Are there permanent
social dominance relationships within the group? Is there any pattern within them?
A few species, notably insects of the
orders ''
Hymenoptera'' (
ants,
bees and
wasps) and ''
Isoptera'' (
termites) show an extreme form of sociality, involving highly organized societies, with individual organisms
specialized for distinct
roles. This form of social behaviour is referred to as
eusociality. Some
vertebrates, most notably the
Naked Mole Rat, are also eusocial.
Some animals whose social behaviour is of particular interest:
★
Humans (''Homo sapiens'')
★
Gorillas (''Gorilla gorilla'')
★
Dogs (''Canis familiaris'' or ''Canis lupus familiaris'')
★
Wolves (''Canis lupus'')
★
Chimpanzees (''Pan troglodytes'')
★
Lions (''Panthera leo'')
★
Bonobos (''Pan paniscus'')
★
Orcas (''Orcinus orca'')
★
Meerkats (''Suricata suricatta'')
★
Hyenas
