Venomous animals use a toxin or poison to kill prey or to defend themselves. They deliver the toxin with specialized organs, like stingers, fangs, hollow fangs, a proboscis, or tentacles. Venomous animals are different from poisonous animals. Poisonous animals (like toads) have a toxin but have no method of delivery; when another animal eats the poisonous animal, the predator may become ill or even die. Some venom (neurotoxin) attacks the nervous system, causing pain, paralysis, and eventually death by heart or lung failure; cobras, stonefish, black widow spiders, and scorpions use neurotoxins. Other venom (hemotoxin) attacks the circulatory system, causing pain, swelling, and changes in the blood; rattlesnakes, vipers and some spiders use hemotoxins. Some of the most venomous animals (the ones with the most potent venom) include the yellow-lipped sea krait (a sea snake), box jellyfish, sea wasp jellyfish, blue-ringed octopus, reef stonefish, the inland taipan, and cone shells. Other venomous animals, like Russell's viper (Vipera russelii) kill more people because they are more aggressive and live near people. Only a few mammals are venomous, including the duckbilled platypus (only males), several species of shrews, and the Solenodon (a small insectivore).
