Colony (biology)

What is a Colony?

In biology, a colony is when many of the same kinds of living things stay close together. This helps them feel safer and find more food. Colonies can look very different, depending on what lives there.

Some colonies are made by tiny cells called bacteria, growing on a surface. Others are made by animals that stay connected, like corals. Even birds sometimes make colonies, like big nests full of families.

Types of Colonies

Social Colonies

Some animals like to live in groups and have special jobs. For example, ants and honey bees work together in big nests. They share food and take care of their young. Mexican free-tailed bats also live in huge colonies, like in Bracken Cave, where millions fly together!

Connected Colonies

Other colonies are made of pieces that stay connected. Some sea anemones can make copies of themselves and stay linked. Plants can also grow copies from stems or roots, making a colony of exact twins.

Tiny Living Things

Very small living things, like bacteria, can grow into colonies on surfaces. Scientists study these colonies to learn more about them. A biofilm is when many tiny creatures work together, doing things no one could do alone.

Living in colonies helps animals and tiny creatures stay safe, find food, and grow strong together.
