Ocean is the origin of , , , which has bred the initial life. So far, there are countless species living in . Essence
Mysterious "Marine World"
, then as the "indigenous" marine life in the ocean, how is supplies freshwater in the ocean?
salty seawater
people are always curious, why seawater is salty, after all, the area of the ocean accounts for 71 % of the surface area of the earth. In fact, it is necessary to talk about "'s culprit ", which can only be said to be the nature. First of all,
first, the river flows through some saline -alkalized land in downstream region, and has carried a lot of salt itself and flows into seawater.
Land saline
follows the volcanic eruption . magma wraps the salt into the sea water. These salt are continuously accumulated to form high -salt content.
seawater itself is like a huge "dead lake" . The water body is not effective in exchanges, resulting in the internal salt cannot be discharged. After
and in the ocean evaporate , they cannot take away the salt. These salt either dissolved into a relatively low salt content, or piled up on the nearby beaches to wait for the next dissolution to the sea water.
Sea Water evaporates
days accumulate, and the salt in seawater will only get higher and higher.
marine life lives in a salty environment, and gives himself "pickled" every day.
But as long as it is a creature, freshwater resources are required. Human has a variety of technologies to fade the seawater. So what technology does marine fish have to replenish yourself to freshwater?
Bioscving
The so -called biosuction is simply to eat other marine life to supply its own freshwater demand .
Marine Law: Big Fish Eat Small Fish
. Since the body's body is , it contains a certain moisture . After the carnivorous marine creature only needs to eat other marine creatures, the body naturally gets fresh water. Supply.
, such as fish, eyes, spinal cord and other parts, contain a small amount of fresh water, even their meat quality contains the water of trace . At this time at this time, some people may ask, with these freshwater supplies, is it really enough for carnivorous marine life needs?
must know, Human Daily Danshui is about
, but marine life is not like land creatures. They do not need sweat to regulate the body. In other words, most of the marine creatures, in the body is not large. Freshwater supply.
Especially for some small and medium -sized meat marine creatures, a certain amount of food brings water to your body is more than enough.
, and these marine creatures that rely on biological supply of water, have a special structure in the body, can effectively use freshwater in the prey as their own use.
Even if there is a small amount of moisture, these marine creatures relying on biological supply can be effectively used. There are thousands of creatures in
ocean, and many creatures and are not suitable for supplies. For example, large marine creatures need more freshwater needs. Essence
or non -meat food marine life. They do not eat other marine creatures, and naturally there is no saying of biological supply. At this time,
marine life "purifier"
, at this time, marine creatures have sacrificed their "magic weapon" , which purify seawater. Among the
, the turtle relies on lacrimal glands to discharge the salt that it eats.
turtles: I have special skills
This is difficult to believe. Turtle crying belongs to physiological phenomenon . How can there be the function of purifying water?
also conducted an experiment on this expert that injected a quarter of the body in a large turtle body. Soon after
, the observer saw that the turtle's tears flowed out. Experts quickly tested these tears and found that the salt content of the tears was more than half higher than the water injected into the water.
experts extracted the water after purification in the turtle body, and found that the salt content of these moisture has been reduced by more than 90 %, which basically reached the level of human edible human edible.
Facing the camera to say hello to
through this set of amazing data. can find that the turtle itself is a natural seawater purification device, and they can use all the seawater.
has this purification function in hand. Turtles naturally do not have to worry about lack of fresh water supply in the ocean. It is worth mentioning that
is worth mentioning that many ocean's reptiles are this kind of lacrimal glands that use it to achieve the purpose of supplies. It is really convenient and practical.
is the most existence among marine life - fish , what kind of "purification device" is used to draw fresh water?
In fact, the fish is mainly self -replenishment through a thing called "secretion cells" .
colorful clown fish
"Smoose Cell" exists in the gills of the fish. The same reason for
, marine fish is also through fish gills. While breathing, it uses "chlorine cells" to filter off the salt division, so that you can get sufficient fresh water. Some fish in
do not worry about their "chlorine cells". After purification, they will also use their kidney to purify the purified seawater for the second time, and will eventually absorb the body.
Whale rely on powerful kidney function to purify in the seawater in his body, and then replenish the body of the body. Everyone knows that
knows that the whale eats the "swallowing jujube" method, swallowing a large piece of sea water into the stomach, and most of them are excreted through the "spray port".
, there is always residual seawater in the body. At this time, the function of the kidney is reflected.
. In addition, the body type of the whale is so large that a single water supply is definitely not enough. They also need to be supplied by a large amount of prey they eat. Under the action of
dual supply , it ensures that you can live well in the ocean.
whale: This day is very comfortable with
and finally there is a supply method that compares Huiqi . Most people can't stand it after listening.
Urea supply
The so -called urea supply is not to drink its own urine, but uses its own urine to convert seawater to freshwater.
urine is inorganic excreted by creatures. How can it be a "conversion device" of freshwater? Next, I will explain it in detail for everyone. Most of
biological excretion is excreted from the body, but urea supply marine creatures are different, such as shark .
Shark, while discharging its urine, retains in the body with a special layer of mucous membrane. This mucous membrane penetrates almost on the whole body of the shark. The existence of urea in
is to make penetration pressure , which makes the penetration pressure of shark body fluid higher than that of seawater, so that when the seawater contacts the shark body, a natural purification barrier is formed.
has this barrier. Naturally, the shark does not need to be supplied by drinking water. It only needs to get sufficient water sources by getting into sea water in your body every day.
at this time, the curious audience can't help but have doubts. Will this method purify the seawater, will it be killed by to kill ? After all, purifying seawater at all times, there will inevitably be the risk of in intake.
does not have to worry about this, because the seawater after the shark -screen barrier is directly connected to directly with the body's cell , eliminating the "middleman".
X cells CG
will not reach related parts such as the stomach . After the
cells reaches saturated, they will not absorb water anymore, just like sponge . After reaching the upper limit that you absorb, water will not consume water. The most important thing about
is that the efficiency efficiency of this barrier is not high. Even if the shark is in the process of replenishment all day long, there will be no excess to death.
is visible that the shark's own "purification device" is subtle. Humans have to sigh that
Humans have to sigh. When facing the living environment, the wonderfulness of the species evolution is precisely because of this evolved gene , and the species in nature can survive for thousands of years.
