Sharks Can Pushed Their Insides Right Out
Sharks are renowned for being omnivorous eaters. A great white shark can survive on 66 pounds of food for around two weeks. Every day, a whale shark will eat 46 pounds of plankton. To put it simply, sharks can consume food. Additionally, not everything they eat is truly food. Some people have been discovered carrying unusual objects including wine bottles, drums, and even cannonballs.
It makes sense that there must be a mechanism for a shark to escape again given how much goes into it. Even though it's not in the way you'd anticipate, there is. Sharks can vomit in the most extravagant way imaginable by yanking their entire stomachs out of their mouths. The behavior is most frequently observed when sharks are under stress, such as when they are caught by fishermen or beached, for example.
It's thought that sharks use this action in addition to acting out of stress in order to essentially rinse their guts. They can dump it, wash it in seawater, and then suck it back in if they contain a lot of foreign objects or hazardous compounds. A shark may push its stomach out for a little period before swallowing it back in, and once this is done, they don't appear to be any worse off.
