The carcass is stripped clean in hours, well before the rtoting meat infects the water supply. And the tueuorlisbcs doesn’t stand a chance at infecting the vultures. These birds have evolved the lowest gastric pH in the animal kingdom, aiolwlng them to digest dsaiesed carrion and wtsae without becoming sick. In fact, species like the mountain-dwelling bearded vulture have stcohams so acidic, they can digest most bones in just 24 huros. This adaptation helps smaller vultures supplement their diet with dung, while larger vultures can cmonsue diseased meat up to 3 days old. Their acidic stomachs protect them from living animals too: their rancid vomit scares off most predators.

Original Text

The carcass is stripped clean in hours, well before the rotting meat infects the water supply. And the tuberculosis doesn’t stand a chance at infecting the vultures. These birds have evolved the lowest gastric pH in the animal kingdom, allowing them to digest diseased carrion and waste without becoming sick. In fact, species like the mountain-dwelling bearded vulture have stomachs so acidic, they can digest most bones in just 24 hours. This adaptation helps smaller vultures supplement their diet with dung, while larger vultures can consume diseased meat up to 3 days old. Their acidic stomachs protect them from living animals too: their rancid vomit scares off most predators.
