infanticide in carnivores
Infanticide is the term given to the killing of a neonate after birth. In zoology, this commonly refers to the killing and in some cases consumption of newborn animals by either a parent or an unrelated adult of the species. In carnivores, it is not uncommon for an unrelated male to commit infanticide to make females sexually receptive. Parental infanticide is sometimes a result of extreme stress by human intrusion.
== Parental infanticide ==
The giant otter becomes extremely sensitive to human activity when rearing its young. 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. In the wild, polar bear mothers will sometimes kill their young because they lack adequate food, but in captivity the main reason is stress.
