Are reptiles aquatic or terrestrial organisms?? Watch
The whole point of amphibians is that they must keep their skin moist so that they do not dry out and therefore must submerge in water/live in humid climates.
Turtles are amphibians, crocodiles and alligators are an exception, they are reptiles as they do not 'need' to be in water, it's just their hunting style and bodies has developed to utilize water, they can quiet happily survive without it but they would probably fail at hunting.
I didn't say reptiles cannot go in water, it is just they are land dwelling animals, humans can go in water but live on land.
That people can get such a basic question wrong shows how poor science education is in this country,
