Ovoviviparity
Ovoviviparity is a reproductive strategy in which embryos develop inside eggs that remain within the mother's body until they are ready to hatch. In this mode, the embryos typically receive nourishment from yolk rather than from a placental connection, and there is little to no direct maternal nourishment during development. The eggs may hatch inside the mother and the young are born alive, or the young may hatch just before or after being released.
This reproductive scheme is distinct from oviparity, in which eggs are laid and hatch outside the body,
Ovoviviparity occurs in several animal groups, most notably among certain reptiles and some cartilaginous fishes, and
The strategy can offer advantages such as protection from environmental hazards and predation during development, enabling
