How do worms survive in stomach acid?
In: 21
The short answer is, they don’t. Worms are highly evolved parasites, and any that live in the guts of animals usually got there as eggs. Parasitic gut worms evolved to have eggs capable of resisting stomach acid. It’s not till they’ve made their way further into the intestines where the acid isn’t a big deal that they hatch into putrid little gut parasites that eat your half-digested food.
