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.
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.
Sea lions breathe just like any other mamal.
Dugongs breathe air using their nose and lungs. Seals, manatees, sea lions, fur seals, walruses, lions, giraffes, zebras, tigers, cats, dogs, buffalos, chickens, roosters, horses, turtles, human beings, eagles, donkeys, monkeys, and many, MANY other creatures breathe air in the same way as dugongs.
no
Whales Breathe air, with lungs. They have to Surface to Breathe, and hold their breath while diving
Lions breathe using their respiratory system, which includes lungs, diaphragm, and air passages. They inhale oxygen from the air and exhale carbon dioxide as waste. Lions have a strong and efficient respiratory system to support their active lifestyle and hunting behavior.
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.
yes, because they have lungs
They Have gills to breath dissolved oxygen underwater.
