Pufferfish Skeleton
You’re looking at pufferfish spines, which are simply modified scales. It’s magnificent by just looking at the picture of the fish’s skeleton. What more if you’re looking at it in real life? They have the ability to puff up to two or three times their original size. Tetrodotoxin, a neurotoxin found in most pufferfish, is 1200 times stronger than cyanide. In Japan, fugu is a delicacy made from pufferfish. Chefs must train for at least three years to prepare it.
