Episode Information

It's over 60 degrees on the ground. Too hot for many animals. Only true heat specialists can withstand these temperatures. Their home is an ancient volcano in southern Germany: the Kaiserstuhl. But in spring it is not yet warm enough for true sun worshippers. They like it hotter - otherwise they are out of action.

The male green lizard ventures out into the sun after hibernation. Now he has to warm up and find a mate quickly before all the females are taken. His journey begins. He has to fight off rivals and seduce a very choosy female to mate with him. Once she has laid her eggs deep in the ground, they are at the mercy of the weather. If the summer is too dry, the baby lizards will die before they can hatch. So even heat specialists like the green lizard are vulnerable in a changing climate.

Red fox babies, on the other hand, try to avoid the heat as much as possible, venturing out of their cool burrows when the sun goes down. Only when they learn to hunt mice will they successfully become independent of their parents. How do heat lovers and heat haters survive in the Germany's warmest spot?
