Hi there! Dr. Riley Davis here, marine biologist with a specialization in elasmobranchii (that's sharks and rays to you!). I've dedicated my life to studying these magnificent creatures, and I'm happy to clear up any confusion about them. You'd be surprised how much misinformation is out there!
So, you're wondering, "How long can a shark survive out of water?" It's a question I get a lot, and the answer, like most things in science, is: it depends.
There's no one-size-fits-all answer because different shark species have different physiological adaptations. However, the most crucial factor determining a shark's survival out of water is its ability to breathe.
Let's dive in a bit deeper:
Gills: The Key to Underwater Breathing
Sharks breathe using gills, specialized organs that extract dissolved oxygen from water. Here's the catch: gills need a constant flow of water to function. On land, a shark's gill slits collapse, restricting oxygen intake.
Think of it like breathing through a straw. Easy underwater, right? But try breathing through that same straw with it pinched shut. That's what happens to a shark's gills out of water.
Species-Specific Adaptations
Some shark species have evolved adaptations that give them a slight edge out of water:
* Intertidal Sharks: These sharks, like epaulette sharks and horn sharks, live in tide pools and are often exposed to air during low tide. They can tolerate short periods out of water, sometimes for an hour or more, by slowing down their metabolic rate and entering a state of reduced oxygen consumption.
* Ram Ventilation Specialists: Great white sharks, mako sharks, and other pelagic (open ocean) sharks rely on ram ventilation to breathe. They must constantly swim to force water over their gills. These sharks are particularly vulnerable out of water and may only survive for minutes before suffocating.
The "Crushing" Issue
Believe it or not, breathing difficulties aren't the only challenge sharks face on land. Unlike bony fish, sharks lack a rib cage. In water, their body is supported by buoyancy. Out of water, their own weight can crush their internal organs.
The Importance of Minimizing Stress
If you ever encounter a stranded shark, it's crucial to act quickly and minimize its stress:
1. Keep it Wet: If possible, gently pour water over the shark's gills to help them function.
2. Support its Body: Handle the shark as little as possible. If you need to move it, support its body weight to avoid internal injuries.
3. Return it to the Water: The goal is always to return the shark to deeper water as safely and quickly as possible.
In Conclusion:
While some shark species can tolerate short periods out of water, it's essential to remember that these are aquatic animals that need water to survive. The exact survival time varies depending on the species and environmental conditions, but prolonged exposure to air is detrimental and often fatal.

The first step in saving a shark is tossing water on its body, which keep tissues alive and gills pumping. In this case, the great white struggled to breathe for up to an hour. He doesn't know how long a shark can survive out of water, but if its gills are dry, it's not breathing.
