pufferfish / blowfish

i just read about this article about pufferfish which known as blowfish too.
as we know blowfish use their highly elastic stomachs and the ability to quickly ingest huge amounts of water (and even air when necessary) to turn themselves into a virtually inedible ball several times their normal size to protect them from predators and some have vines on their skin. Almost all pufferfish contain tetradotoxin,a substance that makes them foul tasting and often lethal to fish. Tetradotoxin is up to 1,200 times more poisonous than cyanide. Shockingly,just by enough toxic in one pufferfish can kill 30 adult humans.

Amazingly, the meat of some pufferfish is considered a delicacy. Called fugu in Japan, it is extremely expensive and only prepared by trained, licensed chefs who know that one bad cut means almost certain death for a customer. In fact, many such deaths occur annually.

we can found pufferfish here

There are more than 120 species of pufferfish worldwide. Most are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water. They have long, tapered bodies with bulbous heads. Some wear wild markings and colors to advertise their toxicity, while others have more muted or cryptic coloring to blend in with their environment.

Poisonous puffers are believed to synthesize their deadly toxin from the bacteria in the animals they eat.
Some species of pufferfish are considered vulnerable due to pollution, habitat loss, and overfishing, but most populations are considered stable.
