What are the charachteristics of reptiles?

Answer 1

Reptiles ought to be cladistically defined as all amniotes. Reptiles arose with the first amniotic eggs. This has implications for traditional Linnean taxonomic distinctions, however, which are arbitrary and fail to show evolutionary relationships. Birds and mammals would be classified as reptiles- rightfully so. If your purpose is to distinguish reptiles from mammals and birds then it would suffice to say that reptiles are amniotes (distinguishes them from amphibians and other more basal types) that do not have distinctive characters of birds or mammals and you might select general features of modern reptiles such as being exothermic and laying eggs. These distinctions can be difficult for exceptions at times since monotreme mammals lay eggs and birds retain dinosaurian scales etc., testimony to their respective evolutionary heritages.

some charachteristics of reptiles are cold blood(this means they count on there environment to warm and cool them selvs),scales, snakes have forcked toungs, but most lizards have fleshy toungs like us. some charachteristics of reptiles are cold blood(this means they count on there environment to warm and cool them selvs),scales, snakes have forcked toungs, but most lizards have fleshy toungs like us.

Answer 3

In general, the characteristics of reptiles are: They have lungs to breath, have thick skin, are ectotherms and have special weird kind of egg.

Specific characteristics of reptiles are:

dry skin with scales or scutes

They are tetrapods, with two sets of paired limbs. Most have five clawed toes on each limb.

spinal columns and a strong skeletal system with a rib cage.

well-developed brain and a central nervous system.

Most have a pelvic region with a minimum of two spinal bones.

breathe with well developed lungs from birth, unlike amphibians that pass through an embryonic stage with gills.

Most have two lungs, except some snakes, which have one.

three-chambered hearts, except crocodiles, which have four-chambered hearts

digestive system is similar to other vertebrates, but the gut, the ducts of urinary and sexual organs lead to one posterior chamber, called the 'cloaca', which has a muscular opening at the base of the tail.

Reptiles lay amniotic eggs, that can survive without water. Most lay eggs, but some give live birth by hatching the eggs inside the body of the mother.

internal fertilization

offspring resemble adults at the time of birth

cold-blooded, the body temperature of reptiles vary with the surrounding atmosphere.

keen sense organs -Eyes located at the front of the head to facilitate binocular vision.

no external ears; eardrum located near the eyes in most

Answer 4

Reptiles are cold-blooded vertebrates with scales, lay eggs, and breathe air. They have dry, scaly skin and most reptiles are able to regulate their body temperature by basking in the sun or seeking shade. Reptiles include snakes, turtles, lizards, and crocodiles.
