Fleeing from enemies, the Virgin possum sometimes resorts to cunning. But more often the possum flees or climbs a tree - it’s safer!
The snakes also pretend to be dead, trying to deceive the enemies.

Which bird has a sponge like breast?

The ruffle bird lives in the deserts of Africa, Asia and southern Europe. There is very little water in the desert, but the chicks do not suffer from thirst, because dad carries them water.

He finds a pond - sometimes hundreds of kilometers from the nest - soaks feathers with water and returns to his babies. And they drink some water from daddy's feathers.
