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.

Researchers have found evidence on maternal care and infanticide in female mice that were pregnant or lactating, when placed in a dangerous or safe environment. Female mice were placed in soiled bedding, with unfamiliar fecal cues of males which modeled a dangerous environment (UMB), or they were placed in a safe environment (NB) with neutral ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
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.
Vertebrate maternal behavior is a form of parental care that is specifically given to young animals by their mother in order to ensure the survival of the young. [1] Parental care is a form of altruism, which means that the behaviors involved often require a sacrifice that could put their own survival at risk. [1]
Teach kids about their bodies, what periods are, why we get them, how babies are made, or you, too, may find yourself scrambling to clarify the word 'smoosh' while running late for dance class."
In the first week of life, infants will sleep during both the day and night and will wake to feed. Sleep cycle duration is usually short, from 2–4 hours. [7] Over the first two weeks, infants average 16–18 hours of sleep daily. Circadian rhythm has not yet been established and infants sleep during the night and day equally. [3]
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infants were born alive during abortion procedures between 2019 and 2022, and, in 2023, Walz signed legislation that repealed most of a ...
