If you're thinking about booping the snoot of the Golden Poison Frog, think again - this little amphibian is packing some serious heat. This tiny amphibian, native to the rainforests of Colombia, boasts enough toxin to kill 20,000 mice or ten grown men. Its bright yellow skin is a warning sign to predators: “Eat me, and you’re done for.”

Indigenous tribes have long used the frog’s potent venom to coat their blow darts for hunting, a practice that has earned the frog its fearsome reputation. Yet, when its not adding to its body count, the Golden Poison Frog is a devoted parent. Males will piggyback their tadpoles to water-filled leaf axils high up in the trees, where they'll continue to care for their offspring until they're ready to fend for themselves.
