Amphibians are four-legged animals that dont have amniotic eggs. That means that camels are viviparous animals. Baby camels are called calves. The albumin, or egg white, provides the embryo with water and protein, whereas the fattier egg yolk is the energy supply for the embryo, as is the case with the eggs of many other animals, such as amphibians. The evolution of amniotic membranes meant that the embryos of amniotes were provided with their own aquatic environment, which led to less dependence on water for development and thus allowed the amniotes to branch out into drier environments. A Bactrian camel, according to the San Diego Zoo, grows to a shoulder height of 6 feet (1.8 meters) and a body length of 10 feet (3 m). Provisional Application Ser.

In amniotes that lay eggs, the shell of the egg provides protection for the developing embryo while being permeable enough to allow for the exchange of carbon dioxide and oxygen. Amphibians lay eggs that must remain moist. The hatchlings from amniotic eggs are more developed than that of amphibians, largely due to the vessels within the yolk sac allowing the transferal of nutrients. The chorion and amnion develop from folds in the body wall, and the yolk sac and allantois are extensions of the midgut and hindgut respectively. This excludes some asexual reproductive strategies, such as plants grown from cuttings and animals that regenerate from cut pieces. Most amniotes, by contrast, are terrestrial and require the amnion to protect the developing fetus under the weight of gravity. Components of the egg: A semipermeable leathery or calcareous shell.
