Swan eggs develop outside the mother's body. After the female swan lays the eggs, she incubates them by sitting on them to provide warmth until they hatch. The incubation period typically lasts about 35 days, during which the embryos develop inside the eggs.

Butterfly eggs develop outside the body. They are usually laid on the underside of leaves to hide them from predators.
Clownfish are born in eggs. They get protected by the male until they hatch. the female can lay up to 1000 eggs.
The egg is made with the embryo inside the body but the duckling inside the egg develops outside the ducks body.
The fertilised eggs develop inside the platypus's body for around 28 days, and are then laid and hatched ten days later.
Oviparous -- reproduction by eggs that develop outside the body -- birds, most reptiles Viviparous -- reproduction via live birth where offspring develop inside the mother's body -- human, most mammals
Eggs develope inside the body before being layed. If they weren't, the "baby" would be born live. Also, eggs need incubation, meaning a male and female have to share genes before the egg gets "fertilized". If that didn't happen, there would be no egg.
It is important to know the reproductive habits of insects. Butterfly eggs are fertilized inside the body of the butterfly.
Viviparous refers to a type of reproduction in which offspring develop inside the body of the mother and are born live, rather than hatching from eggs outside the body. This is common in mammals and some reptiles.
Viviparous refers to a reproductive method where offspring develop inside the body of the parent and are born live, as seen in most mammals. This is different from oviparous species that lay eggs and allow them to develop outside the parent's body.
If eggs are infected by salmonella, the bacteria is inside the egg, not outside on the shell.
Frogs don't need have their offspring develop inside them. So if you were to dissect a frog you would not find the uterus because frogs release sperm and eggs to develop outside the body. Technically, the uterus is the outer shell of the egg...
