Plural of blowfish, a tropical fish that can puff up with water or air when threatened to appear larger and more dangerous.
From blow (Old English blawan, to inflate) plus fish (Old English fisc). The compound name describes the fish's distinctive defensive mechanism of inflating itself.
Blowfish contain tetrodotoxin, one of nature's deadliest poisons—Japan's fugu chefs train for years to remove the toxic parts, yet the fish is considered a delicacy because of the risk!
