Science nerds and social media users are amazed by the plecostomus or suckermouth catfish's fantastic ability to live for a lengthy period without water.
Interestingly, these species and the African lungfish can sleep for years in dry mud until water becomes available again.

How Does Plecostomus Hibernation Work?
The plecostomus is known for being tough and able to adapt to its environment. It lives in the rivers and streams of South America.
When it gets dry, this fish goes into a state of dormancy, like sleep, and lets it live for months or even years without water. Fish can do this fantastic change because they have particular breathing organs that let them take oxygen from the air. This is very important when water sources can dry during the dry season.
In the past couple of years, a video that became popular showed this fantastic way of survival: a plecostomus that looked like it had been mummified was brought back to life with just a splash of water. The fish's unique ability to stay alive for extended amounts of time in dry, hardened mud shows how well it has adapted to its environment.
The plecostomus makes a safe cocoon in the mud that keeps water in and lets air flow through its extra breathing organ, which looks like a gill cavity. This organ allows the fish to live on land for up to 30 hours if its skin stays moist.
Not only can the plecostomus go into a state that looks like sleep, but the African lungfish has also changed its body in similar ways to help it stay alive for long periods when it's not in water.
These ways of surviving show how tough these species are and how well they can adapt to challenging circumstances. The plecostomus has become a popular invasive species in many parts of the world, often doing well in places where people have changed the environment.

How Long Can Other Species of Catfish Live Out of Water?
While the plecostomus and African lungfish have gotten a lot of press for their amazing ability to hibernate, other species of catfish are also very resilient when it's dry. According to a story in Science Times, catfish, often sold in markets in open bowls, can stay alive for a few hours without water as long as their skin remains wet. Because they are so flexible, they can survive short periods of dry conditions, which makes them substantial inhabitants of many different ecosystems.
Catfish usually stay in muddy places when rivers dry up because even a little water is enough to keep them alive for a while. Prolonged droughts, on the other hand, can be hard. For example, popular videos show catfish that look dead but can be brought back to life with water.
The weather has much to do with how long catfish can live without water. In wet places, they can stay out of the water for longer, but in hot, dry areas, they don't have as much time to stay alive.
Catfish's ability to adapt to different environments shows their strength and what those adaptations mean for the world. As climate change continues to change ecosystems worldwide, learning about these ways of surviving can help us figure out how other species might deal with situations that get worse.
Implications and Conservation Concerns
Not only does the plecostomus's ability to hibernate without water shows how well it has evolved, but it also raises important protection issues. As long as people continue damaging natural habitats, the spread of hardy species like the plecostomus could affect local ecosystems that we don't know yet. Their ways of surviving are interesting from a biological point of view, but they also show how important it is to control the environment carefully to keep it in balance.
To protect biodiversity, it is essential to keep these fantastic species' environments safe and lessen the damage that invasive species do. We are still learning about and exploring the natural world. The strength of animals like the plecostomus and the African lungfish is a motivation and a call to action for conservation efforts.
