No. Octopi do not need air to survive. They would die without water, although they have been known to survive for a short time in the air.
No they can,t breath without water they will die
whales can breathe underwater that is why they live in water but sometimes they have to come up to breathe like fish
Humans cannot breathe underwater unaided. It is impossible as we don't have gills. We have to use scuba equipment.
You breathe out more water vapour then when you breathe in
Fish, like all animals, require oxygen to live. They get their oxygen by filtering it out of the water using their gills, so you could say that they breathe water.
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.
Angelfish have gills that extract oxygen from water. Without water, they would suffocate and die.
No, but it is safe to breathe. It would just be oxygen.
If we had to we could get oxygen out of water to breathe. But plants can be ate, or feed the animals we eat. So unless we could find a way to manufacture food out of elements we still need plants.
The frog head is important because the nares/nostrils are located at the tip of the head. Without being able to breathe, the frog could not go under water.
We do not breathe in the water as we can't breathe dissolved oxygen.Dissolved oxygen are oxygen that are dissolved into the water.
It could be because they are sick or there is not enough oxygen in the water.
