How are reptiles able to live on land?
Reptiles reproduce sexually through internal fertilization; some species are ovoviviparous (lay eggs) and others are viviparous (live birth). Because of the development of impermeable, scaly skin, reptiles were able to move onto land since their skin could not be used for respiration in water.
What are the most important characteristics of reptiles?
One of the most important characteristics of animals is how efficiently they gather and utilize oxygen, the molecular fuel that powers metabolic processes. All reptiles, including snakes, turtles, crocodiles, and lizards, are equipped with air-breathing lungs, though different kinds of reptiles employ different means of respiration.
Where do reptiles lay their eggs on land?
Reptiles are ectothermic tetrapods that lay shelled eggs on land and possess scaly skin and lungs. All reptiles, including aquatic ones, lay their eggs on land. Reptiles reproduce sexually through internal fertilization; some species are ovoviviparous (lay eggs) and others are viviparous (live birth).
What makes a reptile different from other animals?
Reptiles have many unique characteristics. Most reptiles, such as turtles, hatch from eggs. Turtles also have scutes instead of scales. The term “reptile” is derived from a Latin word meaning “creeping animals.”
How are reptiles adapted to live 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.
What makes the skin of a reptile unique?
One of the unique characteristics of reptiles is their skin, which is tough and scaly. The following are some of the reptile characteristics. As mentioned earlier, reptiles have a dry skin with scales or scutes. The skin has a few cutaneous glands and high levels of keratin, which prevents water loss through the skin.
Why are reptiles unique in the animal kingdom?
In case of those, who inhabit arid regions, water is further absorbed into the body from the waste in the cloaca and only the remaining waste is excreted. As far as reproduction is concerned, reptiles are unique, because they are the first animals with amniotic eggs, that can be laid on land and not in water.
