Hydric brooding

Hydric brooding is a special way some frogs take care of their eggs. This helps keep the eggs wet so they stay safe.

Frog eggs do not have a hard shell like bird or reptile eggs, so they can dry out easily if left alone on land.

In hydric brooding, male frogs help by putting liquid from their bladder on the eggs. This keeps the eggs moist and safe. For example, the male poison arrow frog Phyllobates vittatus sits on its eggs and releases liquid to keep them from drying out. He checks on the eggs often until they are ready to hatch.

This shows how some animals have special ways to protect their young in different places. It is one of many amazing strategies nature uses to help life continue.
