Fact.

Puffer fish belong to the family Tetraodontidae and are considered a great delicacy in Japan. However, their skin and several organs contain a toxin called tetrodotoxin that blocks sodium channels and prevents them from opening. (If you didn't know, sodium channels must be open to allow transmission of sodium ions into cytoplasm from outside due to the presence of an electrochemical gradient). If a person swallows this toxin, their neurones become unable to transmit action potentials, and they die.



Everything that has gentleness in it is beautified, and whatever lacks it is spoiled.
