Fish have gills instead of lungs. In order to get as much oxygen as possible from the water, the gill must have a large and exposed surface area. Terrestrial animals have lungs, which are not directly exposed to air, and the body can sufficiently replenish any moisture lost from exhaling.

What is the main cause of fish kills in rivers polluted by fertilizers?
The main cause of fish kills in rivers polluted by fertilizers is nutrient runoff leading to algal blooms. These blooms deplete oxygen levels in the water as they decompose, resulting in hypoxic (low oxygen) conditions that can suffocate fish and other aquatic organisms.
Why fishes die when there is an algae bloom?
Most likely, industrial runoff or other forms of pollution have lead to eutrophic conditions (too much phosphate, nitrate, or other chemicals in the water), which were a perfect environment for overgrowth of cyanobacteria (algae). Certain species of cyanobacteria produce toxins that can kill animals (including fish and humans), which killed the fish in the water.
What liquid is taken up in photosynthesis?
Water is taken in and utilized by plants for photosynthesis.
Why can't fish live out of water?
Fish cannot live out of water because they rely on water to breathe. Fish have gills that extract oxygen from water, and without water, they are unable to get the oxygen they need to survive. Additionally, their bodies are adapted to the buoyancy and support provided by water, so being out of water puts stress on their organs and can lead to suffocation and death.
Can a goldfish drown?
A fish would drown in water that is not sufficiently oxygenated.Actually the question is not a silly as it sounds and does not only occur when there is not enough oxygen in the water. Under the right conditions (or in this case, the wrong conditions) a fish can actually drown just as surely as a human can. Drowning is caused by suffocation in a body of water, it is accurate to say a fish that is starved of oxygen while in the water has in fact drowned. Fish breathe by taking in oxygen from the water and if the body of water they are living has a depleted oxygen supply, then the fish must either move to a new, oxygen rich area, or drown. During summer months in particular, the deep lakes' oxygen supply can easily become depleted due to animal respiration and decay of vegetation. This causes large groups of fish to die, as they very often refuse to move out of the oxygen-less region. There are even some species of fish that have developed such complex respiratory systems that they can only breath outside of the water. Fish, such as the Climbing Perch fish, can get out of a body of water and survive on land, but many need to breathe our air as well as gaining oxygen in the water. If these fish are forced to stay under water, they will not gain the necessary oxygen they need to survive, resulting in the fish drowning. The Climbing Perch have a respiratory system that is dependent on our oxygen rich air and the fish will drown if forced to stay underwater for to long, no matter how much oxygen is in the water.
How does a fish feel out of water?
fish die when taken out of the water because they have gills and fish absorb oxygen from the water and when the fish are taken out they die because of them .
Why does a fish die when it is taken out of water?
they cannot breathe out of water.
Why does a fish die when taken out of water?
it depends how long it stays out
Why do fish die when taken out of the water?
Fish, like us, need oxygen to live. However they have gills to taken oxygen from water, whereas we have lungs to take oxygen from the air. Therefore, when fish get taken out of the water, as they don't have lungs they have no way to take in oxygen, so they die.
Would a clown fish die if their not in salt water?
a clown fish will die because it is a ocean fish and with out salt water , it will die in fresh water.
A fish cannot survive if taken out of water?
Fish do not breath air, they do not have lungs like humans or most other land animals.They use gills to take oxygen from water.If you take a fish out of the water it will suffocate and die from oxygen starvation.
What fish in salt water die if you put it in the fresh water?
Most salt water fish will die if placed in fresh water.
Why do fish die in water when the water is too warm?
Will die
Can goldfish be taken from a tank and put into a pond?
Yes it/they can. Care should be taken to let the temperature of the water the fish is/are in slowly equalise with the water in the pond before releasing the fish otherwise it/they may die from temperature shock. I used to place a bucket containing the fish in its/their original water beside the pond and slowly replace a cupfull of water at a time over about 30 mins or so before releasing the fish into its new home.
Why does a fish die when you put it out of the water?
Fish have gills and they absorb the water of the sea, ocean or anyplace with water. It's just like air. Without air we would die. Without water fish would die.
How did a fish die?
water temperature can “shock” the fish and even cause them to die! The water PH and hardness are also critical; the sudden drastic change in either of them can cause fish to die. Gold fish Who's Is Die quickly
Can fish die in salt water?
Fish are not immortal, so they can in fact die anywhere.
