A loach can survive when it leaves the water, what does it breathe with when it leaves the water?

Loaches can not only breathe with gills and **, but also have a special intestinal respiratory function, gills are the main respiratory organs, after leaving the water auxiliary respiratory organs to assist breathing, so they can leave the water without dying such as intestines and **.

There are no large hard scales on the loach, only a layer of tiny scales that are barely visible. It has rounded fins on its tail. This shape is perfect for drilling around in the mud in the water.

Although loaches are fish, they can still live without water. Because in addition to having gills like ordinary fish and being able to breathe freely in the water, it also has better respiratory organs - ** and intestines. The loach's intestines are usually used for digesting food in the first half and breathing in the second half.

Observing the activity of loaches in the water can lead to changes in the weather. When you see loaches tumbling up and down and jumping out of the water from time to time, it's likely to rain.

Loach belongs to the class of fishes and loaches, is a warm water fish, strong vitality, likes to live in rice fields and ponds with water all year round, has a wide range of food habits, and has strong fecundity. It inhabits the bottom of still water and humus silt, and prefers to live on the bottom. It comes out at night to forage for food, and feeds on insects, snails, aquatic plants, and humus.

When there is a lack of oxygen in the water, in addition to the gills, the loach can also breathe with the intestines, which mostly occurs before the sudden change of climate and the arrival of low-pressure rainstorm. In winter, when the water dries up and drills into the mud, it can also sustain life by breathing through the intestinal tube in a humid environment.

Because loaches are endemic amphibians1

Loaches are endemic amphibians.

As long as the environment is humid for two or three days.

Loaches move in the bottom mud or in the bottom silt of the water, and prefer to lie dormant and nocturnal, and their vision deteriorates in the dark environment for a long time. However, the tentacles and lateral lines are very sensitive and play a key role in avoiding enemies and foraging activities.

In addition to respiring with gills, loaches can also perform intestinal respiration, so it has a strong tolerance for low dissolved oxygen. In a water-scarce environment, loaches can survive for a long time as long as the soil remains moist. The loach is very adaptable to the environment, so among the more than 100 species of fish in the loach family, only the loach has the largest number and the most extensive distribution.

Mode of reproduction:

Loaches generally begin to reach sexual maturity at 2 years of age. The breeding season is from April to September, and the peak breeding season is from June to July. Usually, spawning begins at 19 years old and around 24 there is a large amount of spawning and strong reproductive activity.

Loaches are fish that spawn multiple times a year, often at night after rain and sometimes during the day. During spawning activities, loaches are bold and often come to the surface of the water to chase them.

Loach eggs are sticky, and after the eggs are fertilized in the water, they stick to aquatic weeds or debris in the water to hatch, and the fertilized eggs that fall to the bottom of the water can also hatch into loaches. In addition to individual differences, the number of eggs carried by female loach is greatly related to its body length: about 2000 eggs for a female loach with a body length of 8 cm, 7000 eggs for a female loach with a body length of 10 cm, and 13000 eggs for a female loach with a body length of 12 cm.

As long as the environment is humid for two or three days.

When the loach leaves the water, Zheng uses ** and intestines to breathe. Loaches can use gills, eggplant and intestines to breathe, of which the gills are the main respiratory organs, and the intestines are accessory respiratory organs.

The first half of the intestines are used for digesting food and the second half of the intestines for breathing.

The loach is a warm-water fish with a tenacious vitality that can be found in the clear and silent waters of lakes, muddy rice paddies and silt swamps.

Loaches mainly like to move at the bottom of various environments, and generally come out at night to feed, mainly feeding on insects, snails, and aquatic plants.

Answer] :d Answer] d. Analysis: In addition to breathing with the gills like the general spondyloaf, the loach also has a special function of respirating with the intestines, so when the water source is exhausted, the loach can burrow into the mud without seeping to death, and it is to use the intestines to breathe and survive.

Answer]: Kaicha D

Analysis: In addition to the fact that loaches can breathe with their gills like ordinary fish, they also have a special function of respiring with their intestines, so when the water source is depleted, they can cobalt into the mud and not die, which is to use intestinal respiration to survive.

Answer: Hail Trace] :d

In addition to breathing with gills like ordinary fish, loaches also have a special source and function is to use intestinal exhalation to make laughter, so when the water source is exhausted, loaches can burrow into the mud and not die, that is, they use intestinal respiration to survive.
