Frog toxins are in the news with the evidence that Russian opposition leader Alexei Navalny was posioned with epibatidine. Here's more on frog toxins and how poisonous frogs avoid poisoning themselves: https://www.compoundchem.com/2017/09/26/poisonousfrogs/

An infographic titled "The Chemistry of Poisonous Frogs" explains how these amphibians acquire and survive their own toxins. It identifies over 800 alkaloid compounds, like batrachotoxin, which frogs derive from eating ants and mites rather than synthesizing them. A Golden Poison Frog carries enough toxin to kill ten humans by jamming open sodium ion channels, causing cardiac arrest. Frogs avoid self-poisoning through a genetic mutation replacing asparagine with threonine.
