The video revealed how the puffer fish inflated like a balloon when threatened and returned to normal when the danger of attracting much attention.

The video recorded puffer fish that had gradually shrunk to normal shape because the account Clara posted on Twitter last week quickly caused fever, attracting more than 340,000 likes and 132,000 shares. Not only is it interesting, the scene also helps many people mistakenly puffer on puffer fish thanks to the air better understanding this fish, IFL Science reported on 9 October.

The pufferfish body has the ability to stretch up to nearly twice its original size when threatened. This makes them much more difficult to eat, especially with the spiky puffer fish covering the whole body.

Most people think that puffer fish use air to inflate like balloons. But the video shows that the puffer fish spouted a lot of water while falling. This is a proof that the puffer fish swells up by swallowing water quickly into the abdomen. The bulging process causes their skin to stretch to its fullest extent and the spikes stand up. Puffer fish will try to keep the body bloated for long enough for predators to lose interest in eating them.

For a long time, scientists thought that pufferfish kept breathing as they swelled because their gills were hindered. Carrying in some puffer fish even looks like it completely disappears from body changes. However, in 2014, the team at James Cook University and the Australian Marine Science Institute discovered puffer fish continued to breathe oxygen through their gills when bulging.

When not in the water, puffer fish can breathe air into the abdomen. But they will quickly suffocate. According to National Geographic, there are more than 120 species of puffer fish in the world, living mainly in tropical and subtropical waters. The bulging defense mechanism compensates for the slow swimming speed and the awkwardness of puffer fish. Dangerous venom is also a weapon that helps puffer fish fight enemies.

The previously recorded dolphins became excited when poisoning puffer fish. The dolphins chew the puffer fish gently to release the poison that causes a cheerful effect. They even passed on the puffer fish bait to enjoy it.
