Most snakes give birth to live young though a few lay eggs. The advantage of giving birth to live young is that the young are born fully developed and able to fend for themselves. They do not have to wait for the egg to hatch and then go through a vulnerable larval stage. The downside is that it is energetically expensive for the mother to produce large offspring and she cannot lay as many eggs as she could if she gave birth to them.
There are two main ways that snakes give birth to live young. The first is ovoviviparity in which the eggs are retained inside the mother’s body and she provides them with nutrients until they hatch. The young are then born live. The second is viviparity in which the mother provides nutrients to the developing young through a placenta as in mammals. Viviparous snakes are rare and found only in a few groups.
One advantage of live birth is that it allows the young to be born at a more advanced stage of development than if they were hatched from eggs. This is because the eggs are incubated inside the mother’s body and the young are born soon after they hatch. This means that they do not have to go through a vulnerable larval stage as they would if they were hatched from eggs.
Another advantage of live birth is that it allows the mother to control the environment in which her young develop. This is because the eggs are retained inside the mother’s body until they hatch. This can be important in snakes that live in hostile environments as it allows the young to be born in a safe place.
The main disadvantage of live birth is that it is energetically expensive for the mother. This is because she has to provide nutrients to the developing young through her own body. This means that she cannot lay as many eggs as she could if she gave birth to them.
Viviparity is rare in snakes and is found only in a few groups. The main advantage of viviparity is that it allows the mother to control the environment in which her young develop. This is because the young are connected to the mother through the placenta and she can provide them with nutrients and oxygen. The downside of viviparity is that it is energetically expensive for the mother and she cannot lay as many eggs as she could if she gave birth to them.
