A Puffer fish Deflating

Just learned that pufferfish inflate by ingesting water, not by gulping air. But this Gaara-like ‘ultimate defense’ tires them out and puts them at risk for later being eaten: ‘Pufferfish, also known as blowfish, can quickly expand by gulping water into their elastic stomachs. In the movie "Finding Nemo," the pufferfish Bloat inflates in an instant and awkwardly floats away like a beach ball, but it turns out that the fishes' puff has nothing to do with holding in air [...] But inflation comes at a cost, and can increase the fish's oxygen uptake to five times that of resting levels [...] It then takes an average of 5.6 hours before the fish can return to typical metabolic levels. A tired fish is a vulnerable one, and it's likely that pufferfish — known for their deadly poison — may be easier targets for predators after they deflate.’: (https://www.livescience.com/49010-pufferfish-breathe-during-inflation.html)
