as I said beforeit real name is ophiophagus it a greek name it means the snake eater the king cobras diet is primarily other snakes including ratsnakes smaller pythons it will even eat other venoms snakes such as members of the true cobras and much more from the krait family. when food is scarce they will feed of smaller vertebrates such as reptiles rodents and birds. in some cases the king cobra will constrict its prey such as birds with its muscular body it is uncommon though for big meals. the king cobra may live many months with out food it has a big meal because of its slow metabolic rate. the king cobras most common meal would be the rat snake.
