How do sea animals breathe underwater?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
Do all sea animals have gills?
Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians.
How are sea animals able to breathe in water?
Breathing through diffusion of oxygen over the body surface is also found in echinoderms, a group of sea animals that includes starfish, sea urchins, and sea cucumbers. Starfish absorb oxygen as water flows through bumps on their skin called papules, and through grooves in other structures called tubular feet.
Are there any animals that can not breathe underwater?
Mammals such as seals, sea cows and sea otters cannot breathe underwater, because they do not have gills. They have to return to the water surface regularly. Dolphins and whales have specifically adapted their respiratory systems to their environment. They do not breathe through their mouth, but use breathing holes at the top of their heads.
Can a whale or a dolphin breathe underwater?
