Because they are both ectotherms.
Amphibians (class Amphibia; from Greek αμφις"both" and βιος "life") are a taxon of animals that include all living tetrapods (four-legged vertebrates) that do not have amniotic eggs, are ectotherms, and generally spend part of their time on land. Most amphibians do not have the adaptations to an entirely terrestrial existence. There are around 6,000 described, living species of amphibians.
Reptiles (Reptilia; from Latin repere, "to creep") are tetrapods and amniotes, animals whose embryos are surrounded by an amniotic membrane. Today they are represented by four surviving orders: Crocodilia (crocodiles, caimans and alligators), Sphenodontia (tuatara), Squamata (lizards, snakes and amphisbaenids), and Testudines (turtles). Reptiles inhabit every continent except for Antarctica, although their main distribution comprises the tropics and subtropics.
Herpetology (Greek ἑρπετόν herpeton "to creep" and λόγος logos "explanation") is the branch of zoology concerned with the study of reptiles and amphibians.
Reptiles
Amphibians and avians are the most closely related species to reptiles.
Yes, they are close related, but reptiles tend to have scales and amphibians tend to have smooth skin (mostly on tropical amphibians) and even slimy skin.
Reptiles
No, dinosaurs are more closely related to reptiles than amphibians. Both dinosaurs and reptiles belong to the group called diapsids, which are characterized by having two openings in the skull behind the eye socket. Amphibians, on the other hand, belong to a different group called tetrapods.
Neither...They were reptiles. dinosaurs were nether amphibians or mammals they were all reptiles, though they are more closely related to birds.
Amphibians do not have scales; reptiles do.
Reptiles have scales and Amphibians do not.
No. Birds and reptiles are separate from amphibians.
They are generally considered reptiles, though some think they should have their own class.
No. Reptiles and amphibians are two different orders and animals and amphibians cam first. Simply put, the first amphibians evolved from fish and the first reptiles evolved from amphibians.
