If a fish doesn't have gills it can't breathe so it can't get oxygen

Animals like dolphin and whales breath through nostrils also called blowholes which are located at the upper part of their head.

Can fish breath in Coca Cola?
No. Cola is full of CO2. Fish need to extract oxygen from the water using their gills. There are not enough free oxygen atoms in cola.
What evidence is there of rich blood supply in the gills of a perch?
If there is a good blood supply to the gills of a fish it will be breathing and acting normally. As all fish are quite different this will have to be compared to an average happily living fish of the same br The red color of gills is from hemoglobin. Also, think about the size of the gills relative to the overall size that different fish can achieve it also stands to reason that sufficient oxygen must be transported to all the tissues via blood...as well as any expiration gases hence the gills have massive amounts of blood.
How does a trout take in oxygen?
A trout intakes the dissolved oxygen in the water through it's gills - just like any other fish.
What do fish use for breathing?
Breathing system of fish is very efficient as compared to land animals. You have dead space in case of land animals. No such dead space is present in case of fish. Oxygen is only sparingly soluble in water. (4 to 5 ml per liter.) You have continuous flow of water from mouth, which passes through the gills of fish. The very less quantity of oxygen, that is present in water is trapped due to large surface area of gills. It is a great wonder that fish survive with such a less quantity of oxygen in water. The aquatic plants supply the oxygen in almost molecular form that is required by fish to breath in.
How do the organs in the circulatory and respiratory systems of a fish work together to perform a job?
Through their gills, fish take in oxygen that is dissolved in water. This oxygen is then carried by blood cells to the other cells in the fish's body.Oxygen is dissolved in water. The fish needs to get this oxygen into it's bloodstream.This occurs passively by diffusion across the gills. At the gills only a thin membrane separates the blood from the water. Oxygen moves from the water across the membrane into the bloodstream.The greater the concentration difference between the water and blood, the faster the rate of transfer. By pumping blood across the gills (circulatory system), the blood exposed is consistently oxygen depleted, and thus concentration difference remains high and oxygen transfer rate is maximised.If blood wasn't flowing the blood at gills would become oxygenated and then mass transfer would stop. Another way of looking at it is that oxygen would start diffusing out of blood as fast as oxygen diffuses in to blood.Basically, circulatory system keeps 'fresh' blood at gills so it can keep absorbing oxygen.
Fish uses the gills to help survive in the ocean true or false?
Gills allow the fish to extract oxygen from the water. Without oxygen, the fish would die. So the answer is TRUE.
How do fish take in oxygen?
The fishes gills are like filters. when water goes in a fish's mouth, it goes through the gills, which filter out the oxygen.
What does the fish breath with?
All fish breath through their gills, there is oxygen in water, as such, they take the oxygen through their gills.
What does gills help fish do?
Fish use gills to extract oxygen from the water passing over the gills.
Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
What do fish breathe with?
Fish have gills, as they swim water passes over the gills and extract oxygen from the water.
What do clams use for respiration?
Oysters have gills. They absorb oxygen from the water.
Were do fish get there air from?
Fish pass water over their 'gills' the gills extract oxygen from the water.
How do fish get air?
they dont. Oxygen in the water through there gills
Why fish can not ljve without water?
There are some fish that have evolved over the millenia to survive for a while without water because they have developed methods of either using or conserving oxygen. The vast majority of fish however can not get oxygen from air because they have gills rather than lungs and so they can not breath without water flowing over their gills.
Does Nemo have oxygen?
Fish get oxygen from the water using their gills
How is the oxygen taken in by the lungs of a mammal different from the oxygen taken in by the gills of the fish?
the gills of a fish take in oxygen in water while the human lung take in oxygen in the air. I think...
