Amphibians For Sale Why Are Amphibians Born Underwater While Reptiles Are Born Out Of Water?
Why are amphibians born underwater while reptiles are born out of water? - amphibians for sale
I understand the differences, the amphibians and reptiles may be born in their respective environments, but the reason for this difference between the two groups is going on?

For the purpose of reproduction most amphibians are bound to fresh water. Some tolerate salt water, but not true seawater amphibians. Several hundred frog species in adaptive radiations (eg, Eleutherodactylus, the Pacific Platymantines, the Australian-Papua) microhylids and many other tropical frogs, but not all need water. They reproduce by direct development, the ecological and evolutionary adaptation so that they are fully independent free-standing water. Almost all of these frogs live in tropical forests and their eggs hatch directly into miniature versions of adults, through the tadpole stage within the egg. Some species have also adapted to arid and semi-arid, but most of them do not have enough water to lay their eggs. Symbiosis with unicellular algae that live in the gelatinous layer of the egg has repeatedly developed. The larvae (tadpoles or tadpoles) with external gills to breathe. After hatching, the eye begins to gradually transform the adults. This process is called mMetaphors. Typically, animals and lots of water and terrestrial adults, but there are many interesting exceptions to this general form of reproduction.
Most reptiles reproduce sexually. All male reptiles such as turtles have called a double-organ sexual Hemipenis. Turtles have a penis. All Testudines lay eggs, but none of them life-like lizards and snakes. All reproductive activity occurs with the cloaca, the only exit / entrance at the base of the tail where waste eggs and reproductive happens.Amniotic covered with leather, or calcareous shells. The amnion, chorion and allantois are present during embryonic life. No larval stages of development.
I hope it helps!

I'm not sure if anyone really knows, because there were people around before. I suspect that this is not only an adjustment in the vicinity of a water body over a long period of time. If a reptile can get most of their water from food, so you only need an egg that can survive on Earth to terrestrial in its entirety.
