What adaptation do blow-fish have?

Blowfish, also known as pufferfish, have a unique adaptation of being able to inflate their bodies by quickly ingesting water or air when threatened. This inflation helps them appear larger and more intimidating to potential predators. Additionally, blowfish possess highly toxic substances in their organs and skin, serving as a defense mechanism against predators. This adaptation allows them to deter predators and increase their chances of survival in their environment.
