Are Tadpoles Reptiles?

Tadpoles are the aquatic larvae of amphibians, particularly frogs and toads. A common misconception is that tadpoles are reptiles, so let’s answer the question – are tadpoles reptiles?

What is a Reptile?

A reptile is a class of animals that includes modern-day reptiles such as snakes, lizards, turtles, and crocodiles, as well as their extinct relatives, such as dinosaurs. Reptiles all have scales or scutes on their skin, and must regulate their body temperature externally by basking in the sun or hiding in the shade.

What is a Tadpole?

Tadpoles belong to the class Amphibia, of which frogs and toads are the most common representatives. They have smooth skin and short, round, slender bodies, and most have four fins around their body and a long tail. Some have gills and some breathe through their skin.

Are Tadpoles Reptiles?

No, tadpoles are not reptiles. While they have a number of similarities, like external fertilization and the need to live in water, the key difference is that tadpoles have no scales or scutes, so they are unable to regulate their body temperature externally. They are, in fact, amphibians, and do not belong to the class Reptilia.

More Information about Tadpoles:

Tadpoles go through a metamorphosis from a water-breathing form to a land-living organism. During this process, they:

  • Lose their tails and their gills become lungs.
  • Grow four legs which will later become arms and legs.
  • Develop limbs and distinctive frog features such as webbed feet.
  • Replace their external gills with an internal organ that can in turn absorb oxygen directly from the air.

Once fully developed, the tadpole can leave the water, leaving behind the life-cycle of a frog or toad and starting a new terrestrial one.

In Conclusion:

Tadpoles are not reptiles, but rather aquatic larvae of amphibians. They have not scales or scutes, and go through a metamorphosis from aquatic to terrestrial life.
