Amphibians

No. Reptiles are animals. Animals do not have cell walls.

Reptilian eggs often have a hard or leathery shell protecting them - amphibian eggs do not. Amphibians like frogs and salamanders lay eggs that almost look like balls of gel or slime, so they must be laid somewhere moist.

Because reptile eggs have a protective shell, they can be laid in more varied areas than amphibian eggs can.

Yes, all true toads are poisonous. The poison will not harm you as long as you don't get it in your eyes or mouth.

In most cases, no. They eggs are externally fertilized and hatch in the water. There are a couple species that do grow inside, one example being the Sumerian toad.
No, they lay their eggs and have external fertilization.

There is some debate over whether Caecilians are in fact detritivores or carnivores. If they are detritivores then they eat detritus that they find in the soil. Most evidence of Caecilian feeding patterns seems to point to the conclusion that they are in fact carnivores who feed on insects (especially termites) and earthworms.

Reptiles are better suited for dry climates. Amphibians must always be moist, and in order to reproduce, they must have access to water.

the two major group of amphibians are the tailed amphibians and the tailless amphibians

A goanna is a type of monitor lizard found in Australia and Southeast Asia. After mating, it typically will lay up to 25 eggs at a time in a nest covered with soil. The exact incubation period for their eggs is solely dependent on the temperature, which should be kept at a 30 degrees Celsius. As this is not likely in a natural habitat, it can take anywhere from 8 months to a full year for maturation.

their circulatory system is tottaly different from each other as fishes have sinple circulatory system and consists of single auricle and ventricle while all amphibians have double circulatory system and have 3 chambers of heart (one ventricle and two atrium).

Unfortunately, axolotl are a critically endangered species. As for the legality of owning one, that would depend on where you live. In many areas, ownership of an endangered species is prohibited by law. I recommend asking your local vetrinarian for more advice on animal ownership laws in your area.

Any type of frogs are amphibians.

they both have a form of metamorphosis. the butterfly goes through it, and so does a frog, but they do it in different forms

Caecilians are are amphibian as they possess all amphibian characters . Practically we can distinguish amphibian and caecilians by the fact that they are vertebrates and tetrapodes with naked slimy skin .

Yes

No. An animal cannot be both.

Xerocoles are mammals that have adapted to live in deserts. These include many species, mice, rats, foxes, camels and many others.

Tadpoles can be eaten by anything from fish, birds, frogs, snapping turtles. They also enter the food chain when they grow up and become frogs eating flies, dragon flies and other flying insects. They also get eaten by a variety of animals such as cats, birds, snakes, and humans.

The earliest amphibians appeared approximately 250 million years ago.

Amphibian

French also uses the Nahuatl word axolotl to describe it.

Yes, frogs and toads are all vertebrates. They have a backbone and an internal skeleton.

All of our amphibians lay their eggs in water. Most frogs, toads and salamanders like to lay their eggs in small ponds where there are no fish to eat the eggs or young. If the young amphibians grow and change to adult shape quickly, the eggs can be laid in ponds that dry up by late summer. So some amphibians breed in ponds that fill with water from melting snow in spring or heavy rains in summer. They can live in places where there are no ponds or other water for part of the year.
