Venom and poison can both be deadly, but they're two distinct natural weapons.
The terms 'venom' and 'poison' are often used to mean the same thing: a toxic chemical produced naturally by an animal. However, the key difference between them lies in their delivery.
Dr Ronald Jenner, venom evolution expert at the Museum, explains the similarities and differences between these two fascinating toxic substances.
What's the difference between venomous and poisonous?
A fundamental difference between venom and poison is how the toxins enter the body of the victim.
Ronald's rule for telling the difference is straightforward: 'If you bite it and you die it's poison, but if it bites you and you die, that's venom,' he says.
The hallmark of venom is that it's introduced via a wound. It can be injected through a number of means, including teeth, a sting, spines or claws.
'Poison is different as there is no wound involved. It can be absorbed into the bloodstream through the skin, inhaled or ingested,' he says.
