Many animals use neurotoxins to defend themselves and kill prey. [[Tetrodotoxin]] is a poison found in the certain poisonous fishes such as [[pufferfish]] and [[triggerfish]] which blocks the sodium ion channels and prevents an action potential on the postsynaptic membrane. [[Tetraethylammonium]] found in insects blocks potassium channels. Alpha neurotoxin found in snakes binds to acetylcholine receptors and prevents acetylcholine from binding. [[Alpha-latrotoxin]] found in [[Latrodectus|black widow spiders]] causes a massive influx of calcium at the axon terminal and leads to an overflow of neurotransmitter release.
[[Botulinum toxin]] produced by the bacteria [[Clostridium botulinum]] is the most powerful toxic protein. It prevents release of acetylcholine at the neuromuscular junction by inhibiting docking of the neurotransmitter vesicles.
