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.

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 form of exploitation in non-human primates most attributable to adult females is when non-lactating females take an infant from its mother (allomothering) and forcibly retain it until starvation. This behavior is known as the "aunting to death" phenomenon; these non-lactating female primates gain mothering-like experience, yet lack the ...
Within five months of a tigress giving birth, she may become receptive again if her first litter is lost, and for this reason wandering males may commit infanticide. [5] In fear of infanticide, female jaguars will not tolerate the presence of any male, even the father of the litter, once she gives birth to her cubs.
To counteract loss of their pups elephant seals conceive next year's offspring immediately after giving birth to this year's young, but delay implantation for 4 months. Female striped mice ( Rhabdomys pumilio ) in monogamous social groups do not experience reproductive suppression, but those living in communally breeding groups with high ...
Some animals starve to death shortly after birthing their young while others are eaten by their own young -- but these mothers make the ultimate sacrifice. Click through for 10 animal mothers that ...
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
Miscarriage, also known in medical terms as a spontaneous abortion, is an end to pregnancy resulting in the loss and expulsion of an embryo or fetus from the womb before it can survive independently.
