Here are 10 animals that can kill you with one bite or sting:

Box jellyfish

Pufferfish

This is a fish that can inflate its body to several times its normal size when threatened or alarmed. It has spines on its skin that can deter predators, but also contains a deadly toxin called tetrodotoxin in its organs and flesh.

This toxin can cause numbness, paralysis, respiratory failure, and death within hours if ingested. It is considered a delicacy in some parts of Asia, but only trained chefs can prepare it safely.
