Have you ever wondered about the life expectancy of a fish? How long can a fish live out of water before eventually dying?
Many people might assume that this depends on what type of species we’re talking about, and indeed it does.
But surprisingly enough, there are some pretty shocking facts regarding how long a fish can stay alive once removed from their natural habitat.
In this article, we will explore seven pieces of interesting information concerning the longevity of aquatic animals out of their watery home – with some results you may never have expected! Read on to find out more.
Can Fish Breathe Out of Water?
Can a fish breathe out of water? In short, yes, they can – but not for long. To survive out of the water, fish must obtain oxygen from the air surrounding them instead of through their gills (which extract oxygen from the water).
They achieve this by gulping air directly into their mouths and absorbing oxygen into fish’s bloodstream.
However, this air-breathing ability is limited. Fish can only breathe this way for a few minutes before they become exhausted and die due to lack of oxygen.
Fish bring in oxygen through their gills, allowing them to live and breathe underwater.
In contrast to humans, whose respiratory systems are centered around the lungs, fish have tiny blood vessels that line the surface of their gills to process water efficiently.
Do Fish Suffocate Out of Water?
Does being out of water hurt fish? No, it doesn’t – but it can cause them to suffocate if left for too long.
Fish are creatures of the depths, and though some hardy varieties may survive temporarily in the air, most species need to keep their gills wet or risk suffocation.
Once out of the water, their delicate respiratory system quickly shuts down; with no exposure to oxygen-rich air, any longer precious blood vessels become too constricted for survival.
Can Fish Survive on Land?
Can fish live on land? Again, the answer is yes – but only for a short time. While some species can survive in low-oxygen environments, most fish need plenty of oxygen to stay healthy and alive.
When placed on dry land for extended periods, these species quickly succumb to suffocation, heat exhaustion, and dehydration – all of which can be fatal.
For a fish to survive on land, it must be able to access moisture (usually from dew or rain) and oxygen.
Some aquatic creatures, like amphibious fish, possess extraordinary capabilities of hydric adaptations, allowing them to survive on land for extended periods.
Amphibious fish can excrete salt from their bodies and survive in freshwater, so they can also spend short amounts of time being active on dry land.
How Long Can a Fish Live Out of Water?
How long can a fish live outside of water? Fascinatingly, fish have evolved to survive outside of water for varying lengths. Depending on their species, some can remain out of water anywhere from minutes up to months!
The longest surviving fish recorded was a goldfish, which survived for 18 months after being removed from its tank.
This remarkable feat, however, is an outlier. Most other fish can survive anywhere from a few minutes to several hours outside of water, depending on their size and species.

So the next time you take a fish out of the water, remember to take all necessary precautions. Ensure they’re kept moist, get enough oxygen, and aren’t exposed to extreme temperatures – only then will you be able to ensure their health and well-being!
How Long Can Fish Survive Without Oxygen?
How long does it take for fish to die without oxygen? While it may come as a surprise, aquarium fish can stay alive for two days in still water without oxygen – all the while completing their daily tasks and taking occasional breaths of air.
The amount of time for this depends on the species, size of the fish, and environmental conditions.
Can a Fish Come Back to Life After Being Out of Water?
Can fish come back to life after being out of water? Unfortunately, this is not possible.
Once a fish has been outside its natural habitat for too long, it will not survive.
The fish will become weak and lethargic once deprived of oxygen, and its organs may be damaged beyond repair.
Its chances of recovery are incredibly slim, no matter how much time it spends in water afterward.
What Fish Can Survive Out of Water?
What types of fish can survive out of water? While many other fish species can only withstand short periods outside their natural habitats, some are much harder than others.
The mudskipper, for instance, is a fish that can live out of water for hours at a time.
Other species, such as the African lungfish and walking catfish, can survive outside water for short periods.
Lungfish are truly remarkable creatures, with six species possessing limb-like fins which enable them to breathe oxygen.
Some of these aquatic animals rely so heavily on this adaptation that they will drown if deprived of the ability to do so – a testament to their evolutionary success!
Some lungfish have even developed an awe-inspiring capacity. To ensure their survival in harsh environments, they can bury themselves in mud when streams and rivers dry up for months before finally being replenished by rainfall.
These species are equipped with specialized respiratory organs that allow them to breathe air from the surface, and some can also use their pectoral fins to ‘walk’ across the land for short distances.
By understanding the unique adaptations of these species, scientists can gain insight into how fish evolved to live in both water and land environments.
However, it is important to remember that no matter how hardy a species may be, a fish can quickly become weak and disoriented if left out of water for too long.
What Is the Longest a Fish Has Survived Out of Water?
The remarkable mangrove rivulus takes the top spot on this list. Boasting an unheard-of ability among most fish, Defying all odds and expectations held by their aquatic peers, these species can beat long-held notions about air depletion when out of water – surviving up to 66 days!
This feat is enabled by their uniquely adapted respiratory systems that allow the fish to absorb dissolved oxygen directly from the air.
By doing so, the mangrove killifish can survive in conditions and environments that would otherwise be fatal for other fish.
