No they take the oxygen in the water through their gills. However, whale do because they are mammals not fish and all mammals need to breath after all humans don't have gills do they?
none because they never come up to the surface to breathe air and they dont have gills!
Yes; jellyfishes breath through all the surface of their body. Jellyfish cannot breathe air but they breathe water.
By wrigglers I assume you mean mosquito larvae. They have to come to the surface to breathe.
yes
Jellyfish live under the water and get their oxygen from the water itself therefore they do not nee to come to the surface to get air.
Whales come to the surface to breathe air through their blowholes, as they are mammals and need to breathe oxygen to survive. They also come to the surface to regulate their body temperature and communicate with other whales through vocalizations.
No. Turtles do not have gills so they have to come to the surface of the water to breathe.
it doesn't breath
Jellyfish breathe by gas diffusion through all the surface of their body.Jellyfish do not need a respiratory system since their skin is thin enough that the body is oxygenated by diffusion. That means that they absorb the oxygen then need from the oxygen in the water.Jellyfishes breath by gas diffusion through the entire outer surface of their body.
The dragonfly nymphs actually come to the surface of the water in order to breathe. They have gills at the base of their rectum and breathe through their bottom.
Dolphins come up to the surface to breathe.
No, they aren't a mammal like a whale or dolphin so they breathe using the oxygen in the water.
