How Long Can a Shark Stay Alive Outside of Water?
Sharks are obligate aquatic animals, meaning they must live in water to survive. Their gills extract oxygen from the water, and their bodies are adapted to the high pressure and salinity of the ocean. When a shark is out of water, its gills collapse, and it cannot extract oxygen. The shark will quickly suffocate and die.
The amount of time a shark can survive out of water depends on several factors, including the species of shark, the water temperature, and the size of the shark. Smaller sharks, such as dogfish and catsharks, can survive out of water for a few hours. Larger sharks, such as great whites and tiger sharks, can only survive for a few minutes.
In cold water, sharks can survive out of water for longer periods than in warm water. This is because the cold water slows down the shark's metabolism and oxygen consumption.
