No. They don't have lungs. They only have gills.
A Tadpole has gills at first then it morphs into a frog which can only breath in air.
any animal that is on land at some point in its life obtain oxygen the same exact way we do. the only animal that obtains oxygen in a different way is the fish and it obtains its oxygen by filtering the water it swims through between its gills.
Gills are designed to absorb oxygen only from water, and can only work if water is passing through them or they will collapse. When a fish is taken out of the water, the oxygen-absorbing filaments of the gills flatten out and the fish suffocates because it's gills are not made to absorb oxygen directly from air.The simple answer is that gills colapse when removed from water as they are adapted to water which is more dense than air.
A fish! Fish are the only animals with gills and most live in water.
Fish have gills, which are specialized structures that extract oxygen from water as it flows over them. Gills are made up of thin filaments with a rich blood supply that allows for the exchange of oxygen and carbon dioxide. Fish use their gills to absorb oxygen from the water and release carbon dioxide.
Crabs need oxygen, just like we do, but instead of using lungs inside the body they use gills outside the body to obtain it.The mouthparts are visible on the underside of a crab. The gills through which the animal obtains oxygen cannot be seen. They are soft structures under the side of the shell.Their shells help to trap water near their gills so that they can still breathe the oxygen .
Because they can only take up oxygen from water.
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!
We dont, we breath nitrogen and oxygen...but only the oxygen gets used by our bodies.
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.
It filters the water out. Basically the 'breath in' water and take the oxygen from it and the water filters out through the gills
