Limnonectes larvaepartus is a species of fanged frog in the family Dicroglossidae endemic to northern and western Sulawesi, Indonesia. It is unique in that it has internal fertilization and gives live birth to tadpoles. Other frog species that have live birth produce froglets.
Ovoviviparity, ovovivipary, ovivipary, internal oviparity, or aplacental viviparity is a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch.
The young of some ovoviviparous amphibians, such as Limnonectes larvaepartus, are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera Nectophrynoides and Eleutherodactylus bear froglets, with not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth.
Nectophrynoides is a genus of true toads, family Bufonidae. They are endemic to Eastern Arc forests and wetlands in Tanzania, and all except N. tornieri are threatened. Species of the genus are ovoviviparous: fertilization is internal, and the females give birth to fully developed, small toadlets. Together with the West Africa Nimbaphrynoides (which was included in Nectophrynoides in the past) and Limnonectes larvaepartus, they are the only frogs/toads in the world that do not lay eggs. The Ethiopian Altiphrynoides (includes Spinophrynoides), which lay eggs, were also part of Nectophrynoides in the past.
