Animals That Live in Groups

Social animals — from elephant herds and wolf packs to ant colonies and sardine shoals — live in stable or semi-stable groups defined by cooperative behaviour and recognised membership, ranked here by group complexity rather than mere aggregation at food sources.

Updated 25 July 2026

Living in a group and happening to be near others are different things. Fish shoaling for safety in numbers is not the same as an elephant matriarchal herd maintaining decades-long social bonds. This list distinguishes true social groups — with recognised membership, cooperative behaviour and often hierarchy — from temporary aggregations.

Eusocial species such as ants and honeybees represent the extreme end, where most individuals forgo reproduction to serve a colony. Mammalian herds and packs sit in the middle. The ranking reflects social complexity and group stability.

How this list was compiled

Entries are species with documented stable or semi-stable social groups showing cooperative behaviour beyond incidental aggregation. Group size range and social structure — hierarchy, kinship, division of labour — are noted. Temporary aggregations at food or migration are distinguished from persistent social units. Eusocial colonies are included as the most complex form of group living.

Animals That Live in Groups

  1. Honey bee

    Eusocial colony; 10,000–60,000

    Queen, workers and drones with division of labour. Workers forgo reproduction to serve the colony.

  2. Ant

    Eusocial colony; thousands to millions

    Among the most successful group-living animals. Leafcutter ants farm fungus gardens cooperatively.

  3. Naked mole rat

    Eusocial mammal; ~80 per colony

    The only eusocial mammal. One breeding queen and non-reproductive workers in underground colonies.

  4. African elephant

    Matriarchal herd; 8–100

    Females stay together for life. Matriarch leads using decades of spatial memory. Males leave at maturity.

  5. Wolf

    Pack; 5–12 (typically)

    Cooperative hunting and pup-rearing. Alpha pair breeds; subordinates help raise pups.

  6. Lion

    Pride; 3–40

    Related females stay together for life. Males form coalitions and compete for pride access.

  7. Bottlenose dolphin

    Pod; 2–30 (fission-fusion)

    Long-term alliances between males. Fission-fusion societies — group size changes but bonds persist.

  8. Chimpanzee

    Community; 20–150

    Fission-fusion communities with complex politics, alliances and tool cultures passed between individuals.

  9. Meerkat

    Mob; 20–50

    Cooperative breeding with sentinel duty rotation. Subordinates help raise the dominant pair's pups.

  10. Sardine

    Shoal; thousands to millions

    Shoaling for predator confusion rather than deep social bonds. Aggregation rather than true social group.

  11. Flamingo

    Colony; thousands

    Breeding colonies of thousands. Long-term pair bonds within a larger social aggregation.

  12. Prairie dog

    Town; hundreds to thousands

    Complex underground towns with territorial family groups and alarm call communication.

Key facts

  • Eusocial insects — ants and honeybees — represent the most complex group living, with division of labour and reproductive sacrifice.
  • The naked mole rat is the only eusocial mammal, with a breeding queen and non-reproductive worker colony members.
  • Elephant herds are matriarchal and persist for decades, with females staying together for life.
  • Fish shoals are aggregations for predator defence — not the same as mammalian social groups with individual recognition.
  • Dolphin and chimpanzee societies are fission-fusion — group size changes but long-term alliances persist.
  • Group living trades individual risk against shared resources, predator defence and cooperative care of young.

Animals That Live in Groups: frequently asked questions

What animals live in groups?
Elephants, wolves, lions, dolphins, chimps, meerkats, ants, honeybees and many others. Group living ranges from simple shoaling to complex eusocial colonies.
What is eusociality?
The most advanced form of group living — with cooperative brood care, overlapping generations and division of labour, where most individuals forgo reproduction. Ants, bees and naked mole rats are eusocial.
Do fish live in groups?
Many shoal — swimming together for predator confusion — but this is aggregation rather than deep social bonding. Some fish species do form long-term pair bonds or territorial groups.
Why do animals live in groups?
For predator defence, cooperative hunting, shared knowledge of food and water sources, and cooperative rearing of young. The benefits must outweigh competition for resources within the group.
What is the largest animal group?
Ant and bee colonies can contain millions of individuals. Prairie dog towns can cover hundreds of hectares with thousands of residents. Sardine shoals can contain millions of fish.
Are wolves pack animals?
Yes. Wolf packs typically contain 5 to 12 related individuals with a breeding alpha pair. Subordinates help raise pups and hunt cooperatively.
