How did reptiles adapt to life on land?

One of the key adaptations that permitted reptiles to live on land was the development of their scaly skin which contains the protein keratin and waxy lipids, reducing water loss from the skin. Due to this occlusive skin, reptiles cannot use their skin for respiration, as do amphibians; all breathe with lungs.

Which characteristics allow reptiles to live on land and away from water?

The Amniotic Egg

The amniotic eggs of reptiles are very different than the eggs of amphibians. The amniotic egg was one of the evolutionary developments that allowed vertebrates to move permanently onto land and away from the water, which amphibians need to prevent their eggs from drying out.

In what ways amphibians and reptiles have adapted to live on land?

  • Skin that prevents loss of water.
  • Eyelids that allow them to adapt to vision outside of the water.
  • An eardrum developed to separate the external ear from the middle ear.

How do lizards survive in the desert without water?

  • Physiological Adaptations. …
  • Coadaptation.

What advantages do reptiles have?

Reptiles are ectotherms: they depend on their surrounding environment to control their body temperature; this leads to advantages, such as not being dependent on metabolic energy from food for body heat. Reptiles are also poikilotherms: animals whose body temperatures vary rather than remain stable.
