how can tadpoles breathe in water?

Sometimes more than a quarter of the oxygen they use is absorbed directly through their skin. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.

A tadpole (also called a pollywog) is the larval stage in the life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial.

Like their marine cousins, terrestrial pill bugs use gill-like structures to exchange gases. They require moist environments to breathe but cannot survive being submerged in water.

Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins.

There are some amphibia, though, which are salt tolerant – eg Rana pipiens (Tiger frog), Xenopus laevis (clawed frog) and the toad Bufo viridis are found in brackish water; and lagoon and mangrove-dwellers, such as Fejervarya cancrivora (the crab-eating frog), have tadpoles that can survive in seawater.

The gills filter oxygen from the water and dispose of respiratory waste products. Upon maturation from a tadpole into a frog, these gills are lost. Many frogs use lungs to respire, bringing in air through their nares and mouth, into the trachea and then to the lungs for gas exchange and uptake of oxygen.

Many amphibians, such as frogs, undergo a metamorphosis, meaning they begin life in the water and live on land as adults. Defining characteristics of these creatures include moist, scaleless skin and the fact that they are cold-blooded. Amphibians absorb water and undergo gas exchange through their skin.

As they grow and get older, their gills start to recede into their bodies. Legs develop first, followed by arms. Their tails also begin to shrink and they start to eat dead insects and plants in addition to algae. When their lungs develop fully, tadpoles can leave the water and live on land as a new frog.

Tadpoles are born with gills, just like a fish, so that they can breathe under water. They have a big head and a long tail. They definitely do not look like frogs, yet! ... They are a favorite food to fish and water beetles.

Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as rice paddies, slow-moving streams, drainage ditches, and large puddles.

Tadpoles not just baby frogs. ... A tadpole is the aquatic larva or immature form of frogs and toads, after the development of the internal gills and before the appearance of the forelimbs and the resorption of the tail.

Although turtles are aquatic reptiles, they cannot breathe underwater in the same way fish can. Instead, turtles need to surface in order to take in oxygen while swimming, Hess said. “[Turtles] do need to breathe outside of the water,” she said.
