Are there any animals that can breath both air and underwater?

Question

I am having a debate with my friend. Are there any animals that than breahe both air and water??

Answer 1

Eh, actually its not possible.

Crabs:

They have gill chambers which store water, so they get their oxygen from the water after passing amphotheric air through it.


Frogs:

These guys have gills when they're tadpoles, but it changes into gills when they are older.


Water Beetles

They bring along air bubbles from the surface of the pond to build their nest (for the young)

Mudskippers:

Something like the crab

Whales/sealions/penguins:

They hold their breath for as long as 30 minutes
--

Therefore, they either bring their source of air where ever they go, or they just hold their breath.

Answer 2

Yes, there is one that I know of. It is a Fish, called a Betta. Betta fish have adapted lungs because the water,which was originally rice paddies in Asia, isn't in the best shape, as far as oxygen is concerned. However, they still have gills and can breathe underwater for quite a while but have to come up for air to acquire full energy levels.

Answer 3

lung fish ,lives in the mud can walk from mud hole to the next ,on its flippers but is a fish ,with both lungs and gills.
one of the exeptions that have actually got both organs


frogs go though a metamophisis .first they got gills and then they devellop lungs,but they can hold their breath for a long time

salamanders breathe under the water they are amphibians

crocodiles can stay under water a long time got another way of breathing under the water.through their skin

Answer 4

Yes and they are called amphibians. For example frog, newt, toad and salamander. They possess one lung to breathe on land. And they breathe through their moist skin possessing small holes when underwater. Oxygen mixes with the water and passes into their body through the pores.

Answer 5

From: http://www.naturalhistorymag.com/0902/0902_feature.html
Mudskippers are the only fish to conduct many of their major activities��including feeding, courting, and defending territories��on land. In order to manage these feats, they rely on a number of evolutionary specializations. Their prominent eyes, for example, are so well modified for clear aerial vision that their ability to see underwater is diminished. Beneath each eye is a water-filled cup formed from skin folds; as a mudskipper��s eyes become dehydrated by exposure to the air, they can be retracted into this cup to be moistened. With their leglike fins, mudskippers can walk, climb, and leap when out of the water, and thanks to structural modifications in their skin and gill chambers, they are able to breathe both in water and in air.

Answer 6

There is an animal called a lungfish. It spends most of its time in water, but when the water dries up, it digs a hole and lies dormant until the rain comes again. It stores water using a membrane around its body to keep its body moist.

Answer 7

Yes they are known as Amphibians. Like frog it breaths with it's lungs on land and through it's skin in water.

Answer 8

Frogs breathe air as adults but water as tadpoles.

Lungfish can breathe both.

Answer 9

Chuck Norris.

Answer 10

a few........do a search on Yahoo! or Google on amphibians. Whales, penguins, seals, sea lions, walrusses, some fish, dolphins,....think mammals in the water.
