My brother took this photo when he saw a local fisherman selling it in the Philippines. You see, in some parts of Asia they cook this fish and eat it, but that would be after taking out the poison on this fish.
I have not tried it and would probably not to anyway because they said this fish contains tetrodotoxin which can cause paralysis or even death to a person eating it. I also found out on Wikipedia that this maple or puffer fish is said to be the second most poisonous vertebrate in the world, after the Golden poison frog.
I knew some people who have eaten this kind of fish and they said it really taste good, but the question is, would you take the risk in eating this kind of fish?
