Definition

Noun 1. A type of marine fish: Any of numerous saltwater fish characterized by an elongated, often spiny body. They possess the unique ability to rapidly ingest water or air to inflate their bodies into a spherical shape as a defense mechanism against predators. 2. A dangerous delicacy: The flesh (or specific organs) of some species of this fish, prepared as food. It is considered a risky delicacy because several species contain tetrodotoxin, a potent nerve poison primarily found in their ovaries, liver, and sometimes skin.

Usage Examples

• As a type of fish:
  • The diver carefully avoided disturbing the pufferfish resting on the coral.
  • When threatened, a pufferfish can inflate to several times its normal size.
• As a food item:
  • In Japan, specially licensed chefs prepare pufferfish, known as fugu, which is an expensive and potentially lethal dish.
  • Consuming improperly prepared pufferfish can be fatal due to the toxin.

Advanced Usage

• Scientific context: The inflation mechanism is a predator deterrent, and the toxin (tetrodotoxin) is a sodium channel blocker.
• Culinary/Regulatory context: Refers to the strict regulations and specialized training required for chefs to prepare this fish for human consumption safely.
