Pictures of Reptiles, Reptile Pictures

Hundreds of beautiful pictures of snakes and reptiles, including lizards, frogs, turtles, crocs, alligators, and many more.

Reptiles have been around for hundreds of millions of years. They are organized into four living orders including:

  • Testudines (turtles and tortoises)
  • Sphenodontia (tuataras)
  • Squamata (Lizards and snakes)
  • Crocodilia (crocodiles, alligators, caiman, and gavials)

The distinguishing characteristics of reptiles include:

  • The ability to lay eggs with shells
  • Scale covered skin
  • Breath air
  • cold-blooded”

Reptiles are tetrapods, meaning that they have four legs, or have descended from reptiles with four legs. Unlike amphibians, they do not have an aquatic larva stage, though they do usually lay their eggs near a water source or in soil that is moist. Their life cycle varies depending on the species of reptile.  Once a reptile has hatched, they fend for themselves (assuming that they are a species that is mobile at birth).

Reptiles vary greatly in size. The largest reptile is the saltwater crocodile. It averages about 16ft long and weighs about 1100 lbs! The dwarf gecko, on the other hand, is a reptile that is only a half an inch long.

They also have varying life expectancies. Some retiles only live a few years, but some species of tortoise can live to be over 150 years old!
