Question

LIST SOME ADAPTATIONS THAT DISTINGUISHES REPTILES FROM ANPHIBIANS

Answer 1

THE MAIN DIFFERENCE IS THAT AMPHIBIANS ARE DEPENDANT ON WATER. So obviously, adaptation will be based on this difference...

Most reptiles are not as dependent upon nearby water as amphibians. Reptiles have solved the drying-out process by having the skin covered with hard, overlapping scales which help to keep moisture from excaping the body. Reptile eggs do not need to be laid in water because, unlike amphibain eggs, they have a tough shell which helps conserve moisture. Some reptiles may even retain eggs inside the body until they hatch, then giving birth to live young.

reptiles have claws on their feet to help climb, run and dig on land. Because most reptiles are not dependent upon a body of water for reproduction, they can live in places such as deserts where it would difficult for amphibians to survive. Some reptiles, such as crocodilians, many turtles, some snakes and a few lizards have gone back to living in the water, but they breathe air through their lungs and must still emerge from the water to lay their eggs on land

Answer 2

Amphibians such as frogs and salamanders have moist skin without scales. Reptiles like snakes, lizards, and turtles have dry scaly skin. The reproductive system and life cycle of the two are also different. In amphibians, the male places sperm on the female's eggs externally. In reptiles, the male deposits sperm inside the female. Amphibians lay soft eggs in water, while reptiles lay hard eggs on land. Some reptiles even give birth to live young. Baby amphibians change from a larval stage to a mature stage -- like how tadpoles grow up to be frogs. Baby reptiles look very similar to adult reptiles. For more information visit the link below:

Answer 3

Reptiles have to lay there eggs on land, Amphibians in water.

Answer 4

1. scaly skin
2. 3 chambered heart except crocodile having incompletly 4 chambered heart
3. respiration by only lungs.
4.limbs are pentaductile with claws.
5.oviparus and develope direct.
6.metanephric kidenies are present

Answer 5

amphibians are slimey, reptiles are not, amphibians give you warts, reptiles don't, some people are alergic to amphibians, most people don't get an alergic reaction to reptiles. Reptiles are more capable, amphibians arn't.

See? ;)

Answer 6

amphibians mostly keep their skin moist & reptiles do nt . While reptiles breathe 4om lungs & amphibians breathe 4om lungs &gills.

Answer 7

the dry scaly body helps in conservation of water in crocodiles, crocodiles have a very unique heart that enables them to respire when they are under water. those are the only ones i can think of.
