Animals That Mate for Life: A Survival Strategy

Some animals, like wolves and swans, choose to stay with one partner for their whole lives.

This isn't always because of love like in humans; it's often about making sure they survive and have babies that survive too.

Wolves live in packs with a mom and dad wolf, and they help each other raise their pups.

Swans build nests together and raise their young.

Gibbons, small apes, also stay together and help defend their space.

Penguins, especially Emperor and Gentoo penguins, stick together in tough places like Antarctica to share the work of raising their babies.

Beavers are another example; they build homes and work together to raise their kits.
