The amniotic egg allows reptiles, birds and mammals to lay eggs on land without drying out. The class Mammalia is divided into two subclasses based on reproductive techniques: monotremes, which lay eggs, and therians, mammals which give live birth, which has two infraclasses: marsupials (pouched mammals) and placental mammals.See List of monotremes and marsupials, and for the clades and families, see Mammal classification.Classification updated from Wilson and Reeder's Mammal Species .

Anapsids have no temporal fenestrae, synapsids have one, and diapsids have two. The eggs of these species are often laid in water, which protects them from being damaged or squished. Their bodies rehydrate faster than any other mammal. The amnion forms a fluid-filled cavity that provides the embryo with its own internal aquatic environment. The amnion can be found within the egg, as in lizards and birds, or the amnion can simply enclose the fetus within the uterus. Do all arthropods undergo protostome embryonic development? Known as odd-toed ungulates, their rear hooves consist of an odd number of toes. Dromedary camels (Camelus dromedarius) and the domestic Bactrian camel (Camelus bactrianus) were named in 1758 by Swedish zoologist Carl Linnaeus, who only knew of the domestic variety. Flatworms are the most primitive animal phylum to have: Which class of arthropod is terrestrial, have six legs and three body parts? Lacking a protected fluid-filled cavity requires the non-amniotic eggs of amphibians to remain in water. How do camels survive in the Sahara Desert? While this may not be as water-efficient as uric acid, it is much more efficient than excreting straight ammonia, which is what fish and amphibians typically do.
