What animals lay amniotic eggs?
Amniotic eggs are laid by reptiles (such as snakes, lizards, and turtles) and birds. These eggs have a protective shell and membrane that surrounds the developing embryo, allowing them to be laid on land rather than in water. Mammals do not lay eggs with an amniotic membrane; they give birth to live young.
Why do animals that lay amniotic eggs or develop their embryos in a womb care for their young more than those who use external fertilization?
Animals that lay amniotic eggs or develop embryos in a womb typically invest more care in their young because they have a longer gestation or incubation period, which allows for a stronger bond to form between the parent and offspring. This extended developmental phase often requires additional protection and resources, making parental care essential for the survival of the young. In contrast, species that use external fertilization often produce a large number of eggs with minimal parental investment, as the chances of survival are spread across many offspring, reducing the need for intensive care.
How many types of organisms have amniotic eggs?
Amniotic eggs are found in three main groups of organisms: reptiles, birds, and mammals. This adaptation allows these animals to reproduce on land, providing a protective environment for the developing embryo. While most mammals give live birth, monotremes, such as the platypus and echidna, also lay amniotic eggs. Overall, the ability to lay amniotic eggs is an important evolutionary trait among these groups.
Do human being have amniotic egg?
No. An amniotic egg will normally have multiple parts, like a chicken egg. An aminiotic egg also is surrounded by amniotic fluid. A fish egg is a small embryo surrounded by a protective gel like substance that is similar to a shell.
Do most snakes lay amniotic eggs?
Yes, most snakes are oviparous, meaning they lay amniotic eggs. These eggs are enclosed within a shell that allows for gas exchange and protects the developing embryo.

Do warmblooded animals lay eggs and take care of there young?
for an example... ducks & chickens lay eggs and yes, they do take care of their young for a little while. so.. yeah, they do
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.
Why do some animals not need a placenta?
Not all animals have placentas because they lay eggs instead. Only mammals have placentas by the way. Other animals use eggs and amniotic eggs.
What kind of animal that not take care of their eggs and young?
Many animals lay their eggs and leave them - eg the salmon, sea turtles, butterflies. Other animals eg the cuckoos lay their eggs and leave them to other animals to rear.
Why do animals that lay amniotic eggs or develop their embryos in a womb care for their young more than those we use external fertilization?
Animals that lay amniotic eggs or develop their embryos in a womb typically invest more in parental care because their reproductive strategies entail a higher level of energy and resource investment in each offspring. The prolonged development period within an egg or womb often leads to more complex and vulnerable young that require protection and nurturing to survive. In contrast, species that use external fertilization usually release large numbers of gametes with minimal parental investment, leading to lower survival rates and less need for care. This difference in reproductive strategies influences the degree of parental investment in offspring care.
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.
Do lobsters have amniotic eggs?
No. An amniotic egg is a bird or reptile egg, with a shell. Only vertebrates can have amniotic eggs. ^^ By extention, mammals also have amniotic eggs, but they're reduced in placental mammals (live birth). Platypi and echidnas still lay amniotic eggs though.
Does a spider lay amniotic eggs?
No, only reptiles, mammals, and birds have amniotic eggs.
Do frogs and toads have an amniotic egg?
Mammals, birds, and reptiles lay amniotic eggs, and frogs and toads are none of these, so, no, frogs and toads do not have amniotic eggs. Amniotic eggs contain a yolk and aid in gas and energy exchange.
