Amniotic eggs are eggs laid by reptiles, birds, and some mammals that have a protective shell and specialized membranes to provide nutrients, remove waste, and help with gas exchange for the developing embryo. These eggs allow for reproduction on land, as they do not need to be laid in water like amphibian eggs.
amniotic eggs
Parrot eggs are either fertile when they are laid or they are not fertile when they are laid. They have to be fertile and properly incubated in order to hatch.
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: 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 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 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.
well no the eggs need warmth and protection.
of course they will not hatch they need they're warmth from their mothers.
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.
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.
No. All eggs need specific conditions to begin development. Incubation starts at a certain temperature and humidity level.
