What is the type of trait called when the embryos of both mammals and reptiles are protected by amniotic fluid?
The trait where embryos of both mammals and reptiles are protected by amniotic fluid is called amniotic egg development. This type of reproduction allows for the successful terrestrial life of both mammals and reptiles by providing a protective environment for the developing embryo.

What is the taxonomic class in which most species lay amniotic eggs?
Reptilia is the taxonomic class in which most species lay amniotic eggs. These eggs have a membrane that surrounds the developing embryo and provides protection and allows gas exchange. Reptiles, birds, and some mammals are examples of species that lay amniotic eggs.
Mammals and birds are descended from what group of vertebrates?
Mammals and birds are both descended from a group of vertebrates known as archosaurs. This group included early reptiles and gave rise to both dinosaurs (which birds evolved from) and the ancestors of mammals.
What Are the scientific names of the 5 animal classes?
mammals, birds, fish, reptiles, amphibians
What are the four types of animals?
There are four main classes of animals: Mammals (Mammalia), Birds (Aves), Reptiles (Reptilia), and Fish (Chondrichthyes, Agnatha, Placodermi, Actinopterygii, Sarcopterygii).
What do you call the group of mammals to which such species as lions crocodiles and wolves belong?
The group of mammals that include lions, crocodiles, and wolves belong to the category of carnivores, which are animals that primarily feed on meat.
Which animal lacks an amnion?
Amnions surround embryos by encasing them in amniotic fluid. Frogs are animals that lack amnions. Only reptiles and mammals have amnions.
What are three ways that embryo's are protected in sexually reproducing organisms?
Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
Do lions have amniotic or non amniotic eggs?
Lions do not lay eggs; they are mammals, and like all mammals, they give birth to live young. Mammals have amniotic eggs in their evolutionary history, but they do not produce eggs in the same way that reptiles or birds do. Instead, lion embryos develop within the mother's uterus, surrounded by amniotic fluid.
Does a spider lay amniotic eggs?
No, only reptiles, mammals, and birds have amniotic eggs.
What organisms have amniotic cells?
anything that has young that develop in an amniotic sack: reptiles, birds, and mammals
What is one chacteristic that mammals and reptiles share?
Both are amniotic oxygen-breathing vertebrates.
What is an allantois?
An allantois is a sac which develops in the alimentary canal of the embryos of mammals, birds and reptiles.
Does an owl have an amniotic egg?
Mammals, birds, and reptiles lay amniotic eggs, so, yes, owls have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
Does the octopus have an amniotic egg?
No, reptiles, mammals and birds have amniotic eggs because they lay their eggs on land.
Is a amniotic egg a characteristic of a reptile?
It is not so simple. Most reptiles do have amniotic eggs, but a few species give live birth. Conversely, birds and monotreme mammals also lay amniotic eggs.
Do chondrichthyes have an amniotic egg?
No, chondrichthyes, which include sharks, rays, and skates, do not have an amniotic egg. Instead, many species of chondrichthyes reproduce through methods such as oviparity (laying eggs) or viviparity (live birth), with some species having adaptations like the development of embryos in a protective environment within the mother's body. The amniotic egg is characteristic of reptiles, birds, and some mammals, which allows for reproduction in terrestrial environments.
What is a bag of waters?
A bag of waters is another term for an amniotic sac, a sac in which a foetus develops in mammals, reptiles and birds.
