Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates (primate infanticide) but including microscopic rotifers, insects, fish, amphibians, birds and mammals.

Giant otters in captivity must be given privacy when raising their litters as cases of parental infanticide have been reported in the species, potentially caused by human visual and acoustic interference. Though not confirmed, it has been suspected that similar occurrences happen in the wild due to tourists. [1]
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]
Some rodent species (most typically males) will take the chance to kill neonates that are unrelated to them should opportunity permit. There is thought to be several benefits by doing so, which not only include nutrition benefits (particularly where food is in short supply [8]) but also non-direct benefits, such as allowing access to more resources, improving reproductive opportunities and the ...
The Selection of Children in Sparta, Jean-Pierre Saint-Ours, small version of 1785, Neue Pinakothek, Munich.. In ancient times, exposition (from the Latin expositus, "exposed") was a method of infanticide or child abandonment in which infants were left in a wild place either to die due to hypothermia, hunger, animal attack [1] [2] or to be collected by slavers or by those unable to produce ...
Magnus Vinding argues that the lives of wild animals suffering in their natural environment are generally very bad. He draws attention to phenomena such as dying before adulthood, starvation, disease, parasitism, infanticide, predation and being eaten alive. He cites research on what animal life looks like in the wild.
Before the 1980s, health professionals used the phrase spontaneous abortion for a miscarriage and induced abortion for a termination of the pregnancy. [ 25 ] [ 26 ] By the 1940s, the popular assumption that an abortion was a intentional and immoral or criminal action was sufficiently ingrained that pregnancy books had to explain that abortion ...
Pigs are social animals and a female's social support network can play an important role in postpartum piglet-directed aggression. Free ranging pigs form sounders, or small social units, give young gilts the opportunity to observe gestation and parturition and exposing them to normal maternal behavior. [ 7 ]
