12 Most Poisonous Frogs on Earth
The second most poisonous frog in its genus, after the splash-backed poison frog, Peru's red-backed poison frog has a toxicity that is considered 'moderate'. That doesn't mean you can take this little fellow lightly, though: it can still do humans serious injury and kill animals such as chickens. The frog's poison is thought to derive from the neurotoxic venom of the ants it eats and is stored in its skin glands – a great defense against would-be attackers not deterred by its warning colors. Considering the fact that there is only one ground snake (Leimadophis epinephelus ) which has a slight resistance to this and other poison arrow frogs' poison, this critter doesn't plan on becoming a meal any time soon!
