Some animals live alone, but many live in groups. A group of fish is a school, a group of zebras is a herd, a group of wolves is a pack, and a group of bees is a colony. Living together helps animals survive in different ways.
In a group, many eyes watch for danger, so it is harder for a predator to catch one animal. Wolves hunt together to catch large prey. Penguins huddle together to keep warm in the freezing Antarctic. Bees and ants share jobs: some find food, some look after the young, and some guard the nest. Elephants in a herd help to protect the calves.
Worked example
Why do penguins huddle together in winter?
