Reptiles and amphibians have major physical differences. Reptiles have dry and scaly skin, whereas amphibians feel moist and sometimes rather sticky. They are vertebrates and cold blooded like amphibians. As compared to reptiles, amphibians have smooth skin.
How are reptiles different from amphibians?
These are just some of the many differences that make amphibians and reptiles unique species:

What are the differences between reptiles and amphibians?
Reptiles and amphibians have major physical differences. Reptiles have dry and scaly skin, whereas amphibians feel moist and sometimes rather sticky. They are vertebrates and cold blooded like amphibians. As compared to reptiles, amphibians have smooth skin. The skin of most amphibians is not water-proof unlike reptiles. Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. Most amphibians have four limbs. Limbs and lungs are for adaptations of life on land and distinguish them from reptiles.
How are amphibians and reptiles related?
Amphibian vs. Reptile. Reptiles and amphibians are distantly related to each other but in spite of some similarities, they can be distinguished by their physical appearance and different stages of life. Amphibians live "double lives" — one in water with gills and the other on land by growing lungs as they age.
How do reptiles reproduce?
Reproduction. Both reptiles and amphibians reproduce by laying eggs, but reptiles have hard leathery eggs to protect the young ones inside and are often laid in buried, insulated nests. Eggs of amphibians are soft without any type of external membrane and are usually attached to the stems of aquatic plants.
What is the oldest reptile?
Hylonomus is the oldest known reptile was about 8 to 12 inches long with origins 200 million years ago. The first true "reptiles" (Sauropsids) are categorized as Anapsids, having a solid skull with holes only for nose, eyes, spinal cord, etc. Turtles are believed by some to be surviving Anapsids. Shortly after the first reptiles, two branches split off, one leading to the Anapsids, which did not develop holes in their skulls. The other group, Diapsida, possessed a pair of holes in their skulls behind the eyes, along with a second pair located higher on the skull. The Diapsida split yet again into two lineages, the lepidosaurs (which contain modern snakes, lizards and tuataras, as well as, debatably, the extinct sea reptiles of the Mesozoic) and the archosaurs (today represented by crocodilians and birds only, but also containing pterosaurs and dinosaurs ).
How many limbs do amphibians have?
Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. Most amphibians have four limbs. Limbs and lungs are for adaptations of life on land and distinguish them from reptiles.

What is the difference between a reptile and an amphibian?
The key difference between reptile and amphibian is that the reptile possesses a dry skin covered with hardened scales while the amphibian possesses a slime skin without scales.
How are reptiles and amphibians related?
Reptile and amphibian are closely related creatures as their evolutionary pattern is from fish to amphibian then to reptiles. But they differ from how they reproduce and how they breathe air. The eggs of reptiles have a leathery and hard outer shell, which protects the embryo inside while amphibian eggs are soft without the outer membrane. Reptiles breed on land while amphibians breed on water. When the reptile egg hatches, a miniature adult comes out while amphibian eggs are passing a larval stage, which has tails and gills. Most amphibians need water to live while reptiles can live in many places. This is the difference between reptile and amphibian.
What is an Amphibian?

How are reptile eggs fertilized?
The process of how reptilian eggs are fertilized is similar to mammals. The male’s sperm is placed inside the female’s body. The process varies between species, but it is always done internally.
