The lungs of mammals wouldn’t work well for a fish because one breath underwater would fill them with fluid and make them useless. Oxygen is also needed by fish to breathe.
In order to remove oxygen from the water, they use special organs called “gills.” gills are feathery organs that are located in the mouth and are used to suck in air and expel it through the gills. Gills can also be found in many other animals, including birds, reptiles, amphibians, and fish.
The gill is also used by some mammals, such as dogs and cats, to help them breathe underwater.

Can fish run out of breath?
A fish will never get so short of breath that it passes out. It will rest near the sea floor to save energy or surface to search for oxygen. It might seem like a good idea at the time, but it’s not a good idea in the long run.
Can a fish drown?
The majority of fish breathe when water moves across their gills. The gills can be damaged if water cannot move across them. They don’t technically drown, because they don’t inhale the water, but they do die from asphyxiation.
“It’s the most common cause of death for fish in the aquarium trade,” said Dr. Michael J. O’Brien, a professor of aquatic medicine at the University of California, Davis, who has studied the effects of water movement on fish.
Can a fish survive in milk?
Over millions of years, fish have evolved to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecule. Even though skim milk is nine-tenths of a liter, it still wouldn’t be enough to support the growth and development of the fish.
The problem is that the water in which these fish live has a pH of about 7.5, which is about the same as that found in the stomachs of humans. In other words, if you were to drink a gallon of milk, you would end up with stomach acid that would kill you within a few hours.
This is why fish are so sensitive to acid and alkalinity, as well as to the presence of other chemicals, such as pesticides and herbicides, that are present in their environment. And it’s also why they’re so susceptible to disease, because they don’t have the ability to detoxify the chemicals that they are exposed to.
Do fish get thirsty?
The answer is still no; as they live in water they probably don’t take it in as a conscious response to seek out and drink water. Thirst can be defined as a desire to drink water. It is not likely that fish will respond to such a need. In fact, it is likely that most fish do not take water in the same way that humans do.
For example, many species of fish, such as tuna and swordfish, are known to be able to survive without water for long periods of time. This is due to the fact that they have evolved to use their gills to filter the water out of the air, which is why they can survive in such extreme conditions.
In contrast, most other fish cannot survive for more than a few hours without drinking water, and even then, they may only do so in very small amounts. The reason for this is that their bodies are not designed to take in large amounts of water at one time, so they need to constantly replenish their water stores in order to stay alive.
As a result of this, fish can only survive on a limited amount of food for a very short time before they become dehydrated and die.
How do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some even locate their food by smelling the water.
In the wild, fish are usually found in groups of two or three, but in captivity they can be as large as 20 or 30 individuals. They are also often fed a high-fat diet, which can cause them to lose weight.
Do fishes fart?
Most fish use air to inflate and deflate their bladder, which can be found on the sides of their body. The bladder is made up of two parts, the upper part is called the oesophagus and the lower part the urethra. This tube is also known as the sphincter of Oddi. It is located at the base of your spine and is connected to your bladder by a small tube called a duodenum.
Can fishes pee?
Like most living things, fish produce waste from their metabolism. One way to do that is to pee, which is referred to as ecotourism in the fish world. The waste produced by a fish’s digestive system is called faeces. It is made up of bacteria and other microorganisms that live in and on the animal’s body.
The waste is then broken down by the body’s immune system and excreted through the urethra (the tube that carries urine from the bladder to the outside world). This process is known as excretion. Fish excrete a lot of waste and it is not uncommon for a single fish to produce as much waste as a human does in a year. In fact, the average adult male fish produces about 1.5 litres of urine a day.
This is enough to fill a small swimming pool. However, this does not mean that all fish produce the same amount. Some produce more waste than others, and some produce less. For example, some species of fish, such as the Atlantic cod, produce a large amount of fecal matter, while others produce little or no waste at all.
Can fishes feel pain?
The fish do feel pain. It is still a kind of pain, but it is likely different from what humans feel. The fish have nociceptors, which detect potential harm, such as high temperatures, intense pressure, or a sudden change in the water’s pH. When a fish feels pain, it releases a chemical called histamine.
Histamine binds to receptors on the surface of the fish’s skin, causing the skin cells to swell and become red and swollen. This is a sign that something is wrong, and it can also be used as a warning signal to warn other fish of an impending danger.
Can fish drink water?
In addition to the need for water, fish also need oxygen to breathe, which they can get from the air around them.
In order for fish to survive in the ocean, they have to be able to take in oxygen at a high enough rate that they don’t suffocate to death.
The fish then uses the carbon dioxide that it exhaled to make more oxygen for itself and for other fish in its immediate vicinity.
Can a shark drown?
Most sharks need oxygen to breathe, despite being ocean dwellers. They absorb oxygen from the water using their gills, even though they don’t have lungs. Sharks eat a variety of different animals, including fish, crustaceans, turtles, and other marine animals. Sharks are also known to eat other species of sharks, such as rays and raysharks, as well as other fish and marine mammals.
