Most aquatic animals use?
Most aquatic animals use gills to extract oxygen from water. Through a process called gas exchange, they take in water containing dissolved oxygen, absorb the oxygen through their gills, and release carbon dioxide back into the water.
Do organisms take oxygen from the air and the water?
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
How does a crab breathe under water?
Crabs have gills that extract oxygen from the water, allowing them to breathe underwater. They take in water through their mouths and absorb the oxygen through their gills, while releasing carbon dioxide back into the water.
How does a fish without gills get oxygen?
If a fish doesn't have gills it can't breathe so it can't get oxygen
Why do fish have gills?
Gills are a vital part of the respiratory system in fish and other aquatic organisms. Humans (and other mammals) have tiny air sacs in the lungs, alveoli, that are responsible for the exchange of gases to and from the blood. The same is true with fish, except their version of alveoli (gills) are external to exchange gases directly to and from the water. This allows for a process called "countercurrent exchange" by which oxygen is able to diffuse into the capillaries of the gills as the fish swims.Fish without gills is like you without lungs. The intake of oxygen and export of carbon dioxide can't be possible solely through integumentary diffusion in multicellular organisms.Fish have gills because they need to breathe in the water.They take the place of lungs, and permit fish to breathe oxygen from water.fish have gilles so that they can breath under water and also swim and breath at the same timefish have gills to breath underwater. They cant breath on land because gills are for breathing underwater and lungs are for breathing on land.People used to take baby puppies and drown them in the water. They did this because they wanted to see if they were able to survive in the water. So one puppy, by the name of Kelsey, was in the middle of being drowned, and it thought of its inner strength. It then began to shake and the water turned neon red! When the person who was drowning the puppy lifted it up, the puppy had gills and became quite scalish. Then the puppy swam away and it later mated with another fish and they made:GOLD FISHPEACE OUT
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...
How do animals adapt in ocean?
Fish drink the salt water through their gills and the gills avoid the salt water making it fresh.They also take in oxygen from the gills or skin to breath.
Why are gills not suitable for most terrestrial animals?
gilled animals take water into their mouth, siphon out the oxygen and spit the excess out their gills. they have that siphoning organ, which needs water to function, instead of lungs, which can't function in water
What does the shark gill do?
Gills on a shark help it take oxygen out of the water.
What is amphibians breathing method?
please help me what is an amphibians breathing method
How is the oxygen taken in by the lungs of a mammal different from the oxygen taken in by the gills of a fish?

How does an octupus breathe?
An octopus breathes through gills, which are located inside its mantle cavity. As water is pumped through the gills, oxygen is extracted and carbon dioxide is removed from the blood. This allows the octopus to take in oxygen from the water and expel carbon dioxide.
What are the similarities of lungs and gills?
One of the similarities of lungs and gills is that both are used for breathing in and out. Only that gills are found in fishes and young amphibians and lungs are found in birds, mammals, reptiles and adult amphibians.
How do crab breathe on land?
Crabs gills are special they have a part that can help them take the oxigen without needing water.

Why do animals that breathe though gills need to stay in water all the time?
Gills are physical structures that perform a necessary function for those creatures who possess them. Unlike animals that have lungs and are able to breathe air, the animals who possess gills, as a general rule, are unable to breathe air like their lung possessing land counterparts. Gills are present to extract oxygen from water. Unable to simply take a breath of air (for most gilled creatures), the gills filter water, removing from the water the oxygen the creature needs to survive. The vast majority of these animals must remain within water to survive, as their gills are unable to extract oxygen from air like our lungs are capable of doing. Thus, we don't see fish simply exiting a pond and floppings it's way to a new location - prolonged exposure to our atmosphere suffocates them, taking their life. There are a few aquatic animals that have adapted some new tricks to help them survive in more than a liquid environment. Certain salamanders possess external gills around their heads which do their job of getting oxygen from water. However, some have evolved to possess a set of "lungs" which allows them to leave their watery home. All fish are not gilled, as one would assume - at least not all possess functioning gills. Certain larger species of fish must swim to the surface to grab themselves a breath of air (which can be quite a disadvantage as it alerts predators of their location). Animals like the Mudpuppy evolved with both gills and lungs, and modified their fins into sturdier appendages that enable them to move on land if they need to find a better source of water.
