What else can I help you with?
Why do scuba divers need to bring oxygen tanks while fishes do not?
Because fish have gills and can breathe under water and humans do not
How does fishes breathe?
All fish breath through their gills, there is oxygen in water, as such, they take the oxygen through their gills.
Do whales need gills to breathe in water?
No, they do not need there gills because they have air tubes which are connected to their lungs.
What are fishes adaptation?
Fish have several adaptions to help them survive in the water. Firstly, they need gills to breathe, secondly, fins and a tail to help them swim and finally it is important for them to have a streamlined body.
Do oysters need oxygen to breathe?
fishes take in water and remove oxygen from it.....thats how they breathe....
What makes fishes lives in water?
Well they can't breath on land. They have gills either side of their head which bring the fishes blood very close to the tissue surface.This allows Carbon dioxide to leave the blood and Oxygen to be taken up.
Why do you not have gills?
Land mammals do not have gills because there is no water needed to filter out to get oxygen. Fish have gills because they need to filter out water (and other objects) to get the oxygen to breathe.
Can white sharks only breathe underwater?
Yes, white sharks have gills that allow them to extract oxygen from water, which is how they breathe underwater. They need to constantly swim to ensure a flow of water over their gills for oxygen exchange.
How do noctunal fish breathe?
All fish, whether nocturnal or not, use their gills. They don't need AIR to breathe, they need water...
Do you need to have gills to breathe underwater?
Yes, you do need gills to breathe underwater. Gills process the water through them that makes the water allowed to go through the animal's body without drowning them. Gills are the only thing that keep the animals that live underwater, alive. they also don't make you breath the air in-you breath the oxygen in the water!
What do fish use to breathe?
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
How do fish breathe?
they breathe waterVia the gills, by osmosis. The oxygen they need is dissolved in the water.Fish extract the oxygen out of the water using their gills, thus leaving the water hydrogenated, which some plants and animals (marine ones) need as opposed to oxygen so balance is restored. Hope this helps.Fish breathe underwater using their gills.Fish "breathe" by gulping down water. This water passes over the fishes' gills, made up of the same flesh as our lungs (roughly), which extract the water using either active transport, or simply a concentration gradient on a partially permeable membrane, I'm not quite sure. Either way, the oxygen is extracted from the water, and Carbon Dioxide replaced. The water then passes out the slits in the side of the fishes head.This method is very effective, meaning the fish can extract around 80% of the oxygen in water, which is EXTREMELY important, as water only contains 2-5% oxygen, as opposed to 20-something% for air.Also, the ease of which the oxygen is extracted depends on the water temperature, whether it is salty, and other factors. This is why most freshwater fish can't survive in the ocean.
