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.

Infanticide in non-human primates occurs as a result of exploitation when the individuals performing the infanticide directly benefit from consumption or use of their victim. [1] The individual can become a resource: food ( cannibalism ); a protective buffer against aggression, or a prop to obtain maternal experience.
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 ...
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.” ... Yes, some animals can ...
In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside in the case of external fertilization. The fertilized egg cell is known as the zygote. [2] [5]
Scientists hypothesize that this is because many cheetah litters have cubs from different fathers and males would not want to kill any cubs in case they killed their own. [13] The promiscuity of female cheetahs helps to protect the threatened species not only by preventing infanticide but also by bringing greater genetic diversity. [ 15 ]
Minnesota Department of Health documents show that eight infants were born alive during abortion procedures between 2019 and 2022, and, in 2023, Walz signed legislation that repealed most of a ...
Human babies are unique in the animal kingdom due to their large head size relative to their bodies. This has an effect on the birthing process for humans as the bipedal gait of a human causes the birthing canal to be relatively narrow and twisted in the middle.
