Not all venomous animals go unhunted

Grasshopper mice resist painful venom from scorpion prey through genetic changes in their nervous systems.Horned lizards readily consume harvester ants,resisting their envenomed sting with specialized blood plasma.And sea slugs eat jellyfish nematocysts,prevent their activation with compounds in their mucus,and repurpose them for their own defenses.The bombardier beetle is no exception:the toads that swallow them can tolerate the caustic spray that Darwin found so distasteful.Most of the beetles are spit up hours later,amazingly alive and well.But how do the toads survive the experience?That is still a mystery.
