How do seagulls usually stay hydrated?

We all know that seagulls live in the sea for a long time, so they are far away from fresh water, so when seagulls replenish water, in addition to replenishing water through some food, they cannot drink fresh water directly, but by drinking seawater.

Surely many people don't believe that seagulls can replenish water by drinking seawater, everyone knows that seawater is really bitter and astringent, and you can't drink it at all, and the more you drink, the more thirsty you feel. We can see some information that many people are trapped at sea, most of them are dying of thirst, not starvation, they know that the sea is not drinkable. So how do seagulls hydrate with seawater?

In fact, in 1950, a scientist accidentally discovered that the seagull soared in the sky, suddenly skimmed the sea, took a sip of water, circled, and then spit out the water after a while. At that time, he was curious, why can seagulls drink seawater? Then he figured out that the throat of a seagull is a special being.

He found that after drinking water, the seagull did not swallow the water immediately into its stomach, but stored the water in the throats, which are made up of layers of mucosal tissue, which are particularly special, and it can dilute the seawater with a high concentration of salt water through a principle of osmosis, and convert the high concentration of salt water into drinkable fresh water. At that time, after this mystery was discovered, a reverse osmosis technology was also derived.

The principle. It turns out that the seagull has lived on the surface of the sea for a long time, and his throat has evolved the ability to dilute high concentrations of seawater into drinkable fresh water. And this ability is a kind of reverse osmosis principle, and now this reverse osmosis principle is also widely used in important equipment for treating water environments.

It can be said that nature is such a wonderful thing.

Drink seawater because seagulls have a special mucous membrane in their throat that is able to break down seawater into fresh water, and then spit out the remaining high-concentration water.

The seagull basically uses food to replenish water, because it is constantly looking for food, and it does not leave the sea, so it cannot find fresh water, so it can only be replenished by food.

Seagulls replenish water very simply, he replenishes water in his body by drinking water or eating fish, and fish have more water content in their bodies

Since seagulls mostly fly on the surface of the sea, they generally drink seawater to replenish their water.

Hydrate yourself with food and seawater, as seagulls have unique throats that break down seawater into fresh water.

Seagulls actually live near the sea most of the time, far from fresh water, they replenish water, and many times drink seawater.

Because the seagull flies over the sea, it can stay on top of the sea for a while, drink water, and the food it eats also contains water.

The seagull is basically active in the ocean, he feeds and then comes and goes to replenish sufficient water, or goes to drink seawater to replenish water.

Seagulls eat a lot of fish, shrimp, crabs and shellfish, it mainly uses food to replenish water, and it also drinks seawater, so as to ensure that it has enough water.

It's hard to say, because there is no scientific explanation, experts don't study it much, but according to what I've observed, seagulls don't drink seawater, and they should eat fish to replenish their water.
