It swims through the amniotic fluid to the 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.
The amniotic egg has seven different parts that play different functions. The seven parts include the shell, albumen, chorion, yolk, allantois, ammunion and embryo.
The egg tooth helps baby turtles cut through the leathery shell when they are ready to hatch. It doesn't persist much past hatching.
Animals could reproduce fully on land.

The answer is Amniotic egg.
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.
Oxygen can get to the embryo. Of course, it´s also the reason sea turtles lay their eggs on land, it works both ways.
No. Human females have amniotic fluid inside them when a baby is growing in them.
An amniotic egg is an egg which contains an amnios, a fluid filled membrane that surrounds the embryo to protect it. All reptiles, birds, and mammals produce amniotic eggs during reproduction. Those that give birth to live young, including mammals such as chimpanzees, develop an amniotic egg, although it doesn't have a shell, and retain the egg within the body until the offspring is born.
