Depending on environmental conditions, it can shift from viviparous to oviparous reproduction, with production of encysted and dehydrated embryos.
Females are viviparous and give birth to a single litter of up to five offspring.
The viviparous quadrupeds - literally means four-footed mammals bearing living offspring.
These may be viviparous , in which case the mother's body provides nourishment to the embryo, or ovoviviparous, in which case the eggs develop without additional nourishment inside the mother.
Evidence of a carotenoid mutant of rice was suggested by the phenotype of several mutants for which viviparous seeds germinated into albino seedlings.
Two new viviparous mutants showed some signs of precocious germination but did not emerge fully on the cob.
If only these creatures had been able to develop a viviparous capability, so that they could give birth to their babies at sea, they would have an assured future.
The evolution of viviparity , which frees the mother from having to deposit eggs on land, and the tailfirst birth of the young imply that Carsosaurus was well on its way to a more fully aquatic lifestyle.
Some have direct development of terrestrial eggs, and even ovovivipary and true viviparity are known in caudates.
The capacity for uptake by the fetal membranes may well be a primitive sauropsid feature that long predates the evolution of viviparity .
