Amniotic eggs do not necessarily need to be laid in water; rather, they are adapted to be laid in a variety of environments. However, many species that lay amniotic eggs, like reptiles, may choose moist environments to prevent the eggs from drying out, as the eggs are still vulnerable to desiccation. The amniotic membrane provides protection and helps retain moisture, but a humid environment can further ensure the embryo's development is supported. Thus, while water is not strictly necessary, it can provide a more favorable environment for egg survival and development.

What are amniotic eggs?
Eggs laid by mammals, birds and reptiles. They have a membrane that contains fluid. There is amniotic fluid around the embryo. It also has a protective shell that provides air to pass through.

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.
Advantages and Disadvantages of Amniotic Eggs?
advantages: gas exchange is possible via the chorion, there isn't a larval stage, the egg offers some protection disadvantages: must be laid on land, stationary / must be protected from predators
When the angelfish lays the eggs and you remove them off the spot where they were laid?
When angelfish lay eggs and you need to remove them for safety or breeding purposes, gently scrape them off the surface using a flat tool, like a credit card. Be careful not to damage the eggs, and transfer them to a separate, prepared tank where water conditions are similar to the main tank. Monitor the eggs closely for signs of fungus or contamination during their incubation period.
The feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction is?
The amniotic egg is the feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction. The amniotic egg has protective membranes and allows reptile embryos to develop on land, reducing the need for water for reproduction.
When a wild female quail laid many eggs in a potted container on a patio She has not been there for 2 days Can the eggs still be hatched?
well no the eggs need warmth and protection.
Your cockatail has laid eggs at the bottom of her cage will they hatch?
of course they will not hatch they need they're warmth from their mothers.
Why do turtles lay their eggs on the shore and not anywhere else?
Because the eggs need to be in a place far enough away from water so the eggs can develop, yet close enough for the young turtles to return to the sea once they hatch. If they were laid far inland, there would be more opportunities for predators to pick off the young as they made their way to the water.
Does a female turtle egg need to be fertalized by a male after laid?
Turtles are not fish. The eggs are fertilized when the turtles mate, if a female lays eggs before mating then the eggs will be unfertilized and will never get fertilized.
Do quail eggs start developing when they are first laid?
No. All eggs need specific conditions to begin development. Incubation starts at a certain temperature and humidity level.
