Reptiles

Let's learn about reptiles characteristics in today's learning.

Reptiles are animals in the (Linnaean) chic Reptilia. They are characterized by breath air, laying tough-shelled amniotic eggs, and accepting derma covered in scales and/or scutes. Reptiles are classically beheld as accepting a "cold-blooded" metabolism. They are tetrapods (either accepting four limbs or getting descended from four-limbed ancestors).

Next time i will discuss the uses of water.
