This behavior is known as the "aunting to death" phenomenon; these non-lactating female primates gain mothering-like experience, yet lack the resources to feed the infant. [1] This behaviour has been seen in captive bonobos, but not wild ones. It is not clear if it is a natural bonobo trait or the result of living in captivity. [2]

This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental.
Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals ) live longer than wild animals. This may be due to the fact that with proper treatment , captivity can provide refuge against diseases , competition with others of the same species and predators .
