Terminology
Poisonous substances introduced into the body by sting or bite are known as venoms. In everyday usage, a poisonous organism is one that causes harm when ingested or touched, while a venomous organism uses venom actively to incapacitate prey or deter predators. Although rare, some organisms may be both poisonous and venomous.
