The Skeleton of a Pufferfish

Pufferfish are quite interesting creatures, beyond their ability to inflate up to three times. 120 pufferfish species exist and the majority are marine-water fishes. They are a delicacy in Japan and China but given that they are toxic to predators, including humans, only trained chefs can masterfully handle the fish.

The picture depicts what a pufferfish skeleton looks like, and their spines are on full display. Unlike most other fish that have scales, puffers have spines that are not visible until they get inflated. They contain tetrodotoxin which is a neurotoxin said to be 1200 times more potent than cyanide.
