What Classification Are Reptiles?

Reptiles, also known as reptiles (lat. reptilis = “to crawl”), are an estimated 10,000 species of vertebrates. The first reptiles populated the planet more than 300 million years ago in the Permian geological era.

There is often confusion between reptiles and amphibians. In fact, there are some similarities with the amphibian class, including poikilothermy. The clear distinguishing feature is the metamorphosis. While amphibians change their external appearance in the course of their metamorphosis, reptiles already hatch in their final ‘form’ and therefore no longer change.

Reptiles are divided into four orders:

  • Tuataras (considered ‘Living Fossils’);
  • Crocodiles (alligator, caiman, crocodile);
  • Turtles;
  • Scaled Creatures (all snakes).

By the way: The already extinct dinosaurs also belong to the class of reptiles.

Characteristics of the reptiles:

All reptiles (creeping animals) share common characteristics, including four-leggedness, poikilothermy, and pulmonary respiration. However, there may be occasional deviations. This means that not all of the characteristics listed here have to apply to a reptile.

Respiration: Reptiles breathe through the lungs (pulmonary breathing)

Legs: All reptiles have four legs. In snakes, however, these have receded to such an extent that they are practically no longer recognizable.

Egg: The eggs of the reptiles are covered by a lime shell so that no water escapes. This is the only reason why reptiles can lay their eggs on land.

Birth: Some reptiles lay eggs, others give live birth to their offspring (e.g. sea snakes).

Reproduction: In almost all reptiles, reproduction occurs as part of copulation, so the eggs inside the reptile are fertilized.

Skin: Reptile skin is usually dry.

Hearing: Reptiles do not have good hearing. They have what is known as Jacobson’s organ, which they use to detect very subtle smells.

Cloaca: Reptiles have only one exit for the urethra and anus, the so-called cloaca.

Poikilotherm: The ambient temperature determines the body temperature. Cold-blooded animals such as reptiles can no longer move when the temperatures are too cold.

Scales: Horn scales or horn plates form armor against mechanical influences.

Tail: All reptiles have a tail or a vestige of a former tail.

Vertebrates: As vertebrates, reptiles have a spine.
