Sharks breathe with gills, just like any other fish.
Dolphins are mammals, they breathe with lungs. They can't breathe under water. But they're really good at holding their breath, so they only need to surface every few minutes for a new breath.
Sharks can't breathe air and will suffocate fairly rapidly if lifted out of water. They're really only equipped for a watery Life.
Sharks are fish, and breathe with gills. Dolphins are mammals, breathe with lungs, and can't breathe underwater. They breath at the surface, then hold their breath - which they're really good at - while diving.
They can breathe under water for as long as they want because the have gills and can get their oxygen from the water. In fact, they'll die within minutes if removed from the water.
No mammals can breathe underwater. All mammals, including sea mammals, must breathe above the surface of the water. This is why marine mammals such as dolphins and whales frequently come to the surface.
They don't. Dolphins and whales breathe air just like we do. They can hold their breath for a long time, but they come up to the surface to breathe.
No. Sharks are fish, they breathe water through their gills.
Most fish do... unlike the betta fish they can breathe water and air. Dolphins and whales are an example of ones that breathe only air. Sharks, gold fish and other fish have to breathe water.
Kinda-sorta. Sharks are fish, they use gills to get oxygen from the water. So it's a kind of breathing even if there are no lungs involved.
They are mammals and breathe to breathe. Although they can hold their breath for a long tome and at great depth, at some point they must return to the surface for air. This is also true of whales because they are mammals but not sharks because they are large fish.
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
They use a blow hole to breathe in/out air when the surface the water.
They don't. Dolphins have lungs, and have to Surface to Breathe. Thye hold their breath while diving.
Fish have gills so if it was out of water it will breathe through its mouth. The gills are used to breathe under water like sharks
