Fish breathe with gills. By the way, whales do not. They breathe air, because they are mammals.
Animals that are covered with scales, breathe with gills, and have a tail fin belong to the class Osteichthyes, which includes bony fish.
A salamander has both lungs and gills to breathe underwater. I found a good site if you want to read more about them.
They have gills. They take in water and separate the oxygen from the water.
No, they're exclusively aquatic animals, mostly in high saline water (the sea). They're of one of the oldest and more primitive fish lineages, don't really have the gills to breathe in non moving water and can't breathe air either through their gills or skin, so they couldn't be land or even amphibious animals.
Breathe under using gills, not lungsLive in waterHave scales and fins (No hair or fur)Cold bloodedLay many eggs
The primary function of external gills in aquatic animals is to exchanges gases. However, gas exchange is more difficult with external gills.
are u a moron?? fish have GILLS the BREATHE under water
The animals cannot breathe
There are several ways animals breathe. Most mammals, reptiles and birds use lungs to do so, while some amphibians and fish use gills. Some fish have an air bladder, which is kind of like a primitive lung and allows them to live in oxygen depleted bodies of water. Other amphibians and more primitive creatures can respire through their moist skin.
The primary aquatic animals man the animals that live in water. Such animals have gills and their body anatomy allows them to survive under water. Some examples include fish, snails, frogs, whales and many more.
Gills or gill-like organs are found in various groups of aquatic animals, such as mollusks, fishes, crustaceans, insects, and amphibians. Please see the related link below for more information:
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
