air
Octopuses breathe water through gills, not air.
Yes, beavers breathe through lungs, like most mammals. They have adapted to their aquatic environment by being able to hold their breath for extended periods while swimming underwater. However, when they surface, they breathe air using their lungs, just as humans do.
They breathe through breathing tubes that will stick out of the water to get oxygen from the air.
Yes, octopuses can breathe out of water. They have gills that extract oxygen from the air, allowing them to breathe when they are not in the water.
Otters can't breathe under water. They're mammals, they breathe air, with lungs. When they dive, they hold their breath.
They use a blow hole to breathe in/out air when the surface the water.
No, the air you exhale is nearly saturated with water vapor. During breathing, air is exposed to the moist tissues of the sinus, trachea, and lungs, and will typically contain substantially more water vapor when exhaled. The only exception would be for air that is already saturated or supersaturated with water.
Sea lions breathe just like any other mamal.
Dolphins are mammals. They breathe air with lungs, pretty much just like you and I. They can't breathe water. When they dive they hold their breath.
No, sharks do not breathe air. They have gills that extract oxygen from the water as it flows over them, allowing them to extract oxygen from the water and breathe efficiently in their underwater habitat.
Betta fish breathe air....yes... that's right... they breathe air. They breathe air because they have an organ by their gills that is called the Labyrinth's Organ which allows them to breathe air. They breathe air by coming up to the surface of the water. Then they gather air in their mouths and hold their breath underwater.
That is where it breathe in water and if you blew air into its gill you would drown it in air
