Whales Breathe air, with lungs. They have to Surface to Breathe, and hold their breath while diving
Otters can't breathe under water. They're mammals, they breathe air, with lungs. When they dive, they hold their breath.
They breathe air through their nostrils. They simply hold their breath when they need to dive.
As far as I am aware, there is no sea creature that needs to be physically on land to breathe, but there are a number of sea creatures that can breathe air, either exclusively or in tandem with breathing in water. All sea mammals and reptiles (such a whales, dolphins, porpoises, walruses, seals, sea lions, crocodiles, turtles, sea snakes, etc.) can only breath air, so they must surface. There are a number of fishes, like lungfishes and mudskippers than can both breathe in water and in air.
yes, because they have lungs
Sea lions are mammals, just like otters, dolphins and whales. They breathe air through lungs while at the surface, then hold their breath as they dive. If they wouldn't be able to get back to the surface soon enough, they will drown.
It is difficult to breathe on the summit of Mount Everest because there is less air to breathe than what is at sea level.
Because the air is thinner up there. There is less oxygen in the air, so it is harder to breathe.
Sea turtles are among the world's most ancient vertebrates. ... Sea turtles are reptiles, like snakes and lizards, and breathe air.
No, they cannot. All living things need oxygen to breathe. Sea Monkeys (and all fish) breathe the oxygen that's in the water. By not purifying the water, they will eventually breathe all the air That's in the tank, and then suffocate.
No they do not. The respire like sea stars and other echinoderms. Lungs only ever breath air.
They breathe air with lungs.
