The Evolution of Reptile

Cold Blooded Animals
Most reptiles are cold-blooded vertebrate animals. Cold-blooded animals also known as poikiloterm. This type of animal has body temperature that is influenced by the environment. No wonder if we are visiting a safari park, we often see crocodiles that are basking their bodies in direct sunlight.
He tried to regulate his body temperature to suit his environment. Reptiles have an inner body temperature that is higher than their outside body temperature. Not only reptiles, the Fish and Amphibians are also included in Poikiloterm groups of animals.
Vertebrates are animals that have a spine. Reptiles have a spine with the central nervous system. Central nervous system includes the brain and spinal cord.
Reptiles breed by laying eggs for childbirth. Those eggs have embryos which are enveloped by amniotic membranes. Amniotic membranes are special membranes just like protective shells that helps their children survive. Survive from predatory attacks, natural damage, drought, and pathogenic bacteria. That’s why reptile eggs are called amniotic eggs.
This amniotic egg has four bags inside the shell. The first bag called chorion, transport oxygen from the shell to the embryo and take away carbon dioxide from the embryo to the shell. The second bag is amnion. Amnion keeps the eggs from drying out.
Then, the third bag is allantois that fused with chorion to form the membrane just like a lung that carries oxygen and carbon dioxide to and from the embryo. And the last bag is an egg yolk sac that digests nutritious egg yolk for a developing embryo.
