In some extraordinary wildlife footage I was privileged to watch, a small impala antelope in Africa races away from a pack of wild dogs into a river where she is immediately seized by a large crocodile.
Suddenly a hippopotamus rushes to the rescue of the dazed antelope. The crocodile releases his prey and the hippo then nudges the small animal up the bank of the river and follows her for a few feet until she drops from exhaustion.
Instead of leaving, the hippo then helps the little creature to her feet and, opening his mouth wide as possible, breathes warm air onto the stunned antelope. The hippo does this five times before returning to the forest.
There is no possible explanation for this remarkable behavior except compassion.
