The hooded pitohui. The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact.

The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested. They are often distinguished from venomous animals, which actively inject their toxins (called venom) into their victims through a venom apparatus such as fangs or a stinger. The only difference between poisonous animals and venomous animals is how they deliver the toxins. This list deals exclusively with poisonous animals.
