All crocodiles are meat eaters and feed in water. They are particularly successful in catching smaller animals because they can float up very close to their prey without being seen. They catch animals at water holes in this way and, holding them under water, they back off into deeper water until the prey drowns. Crocodiles tear pieces from their victims by gripping with the teeth and turning over and over. Crocodiles mysteriously attack man in only some areas of Africa. They are probably more aggressive when protecting. a nest or when the water is drying up. Older ‘rouge’ specimens perhaps become used to catching domestic animals in a particulars locality and eventually attack the men who tend them.
