Some female amphibians protect their eggs and the young by carrying them inside their bodies.

The alpine salamander passes through all the stages from an egg into the tiny adult inside

its mother’s body. The animals live in low temperatures.

It takes two to three years before a litter of just two salamanders is born.

The young ones are able to live on land and breathe air immediately.

Fire salamanders also grow inside their mother’s body.

They are born in water and have gills for breathing.
