Why do barramundi survive for four hours after they leave the water?

Because the barramundi has a breathing structure similar to that of human lungs, it is able to breathe on land for up to four hours, which is its evolutionary path, and if the barramundi continues to evolve, it may become a land creature in the future.

Since the African lungfish has lungs that most aquatic animals do not have, they can continue to absorb oxygen without water and keep their body functions running. But the lungfish is still an aquatic animal at heart, and when it leaves the water, its other organ activities are gradually lost, so four hours is also a lot.

Reason: The lungfish is a special fish that can breathe with gills when in the water, butIt has a special swim bladder, its swim bladder has the function of the lungs in terms of physiological structure, which are multi-branched vascular networks and spiral valves, with short swim bladder tubes and esophageal communication, which can absorb oxygen and discharge carbon dioxide with the swim bladder when hypoxia, so that the lungfish can breathe air directly after leaving the water. During the dry season in Africa, barramundi burrows into the wet mud and curls up in small burrows; In order to prevent it from drying out, it will be from**Secrete special mucus to wrap around the whole body, form a waterproof layer, leave only a small hole to breathe, and use your muscles and fat as nutrients to surviveand reduced the metabolic rate to one-sixtieth of its original level, which is about less than 2% of normal.

Why can barramundi survive for four years without eating or drinking?

<> African barramundi can live for about three to five years in the soil. This fish lives on the African continent, and due to the local climate, it will enter the Sui Jian dry period every once in a while, when the rivers dry up and the fish are exposed to the air. Lungfish, on the other hand, can breathe through their swim bladders, so they do not die.

They then burrow into the mud to keep their bodies hydrated and then go into a dormant state.

This is because this fish uses its gills to breathe when it is in the water, and when it is on land, it can breathe with its lungs, so it can survive after leaving the water for a long time and returning to the water.

Because this fish will secrete mucus to moisturize ** when it dries up, so that it can get a dormant state, so its vitality is very tenacious.

Because the vitality of the African barramundi is very strong, when there is no water and food, it will reduce its metabolism as much as possible, waiting for the opportunity to wake up.
