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.

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]
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]
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.”
Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
The males then forcefully insert their genitalia into the female vulvar opening. [3] In the newt species Notophthalmus viridescens, males carry out a courtship behavior called amplexus. It consists of males capturing females that do not want to mate with them and using their hind limbs to grasp the females by their pectoral regions. [5]

"To their credit, they unanimously said, 'Do the other ending, do the one that's true to the book,'" Sanders recalled. "That's a tougher ending because you have got to stick the landing."
