Well you see fish breath through things called gills so they don't need lungs to breath. Whales have huge holes at the top of their heads so when they need to breath they squrt out water from those holes.
Some animals, like some vermiforme worms breath through their skin, but it's not an efficient way of breathing so body size and metabolism is a limiting factor. Bigger and more evolved animals such as frogs use skin breathing as complementary.
Fish do not have lungs
umm their nose!
Like humans, they have lungs.
Bats are mammals and breath using lungs.
Mammals breath using lungs.
No. They breath using their lungs or with their lungs, but not "through" their lungs. They do however breath "through" their blowholes (to get the air in and out of their lungs).
No, in general lungs are only good for animals that breath air. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
Yes, they breath in ond out using their lungs
Whales breath air using their lungs.
A hawk is a mammal; mammals breath using lungs.
star fish using lung to breath
Mammals breath air using lungs.
Reptiles breath using lungs.
Neither, in general lungs are only good for animals that breath air and fins are used for swimming not breathing. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
A whale is a mammal and needs to come to the surface and breath air using two lungs.
