Sexual cannibalism is a behaviour in which a female animal kills and consumes the male before, during, or after copulation. Sexual cannibalism confers fitness advantages to both the male and female. [78] Sexual cannibalism is common among insects, arachnids [79] and amphipods. [79] There is also evidence of sexual cannibalism in gastropods and ...
In evolutionary psychology, people often speak of the four Fs which are said to be the four basic and most primal drives (motivations or instincts) that animals (including humans) are evolutionarily adapted to have, follow, and achieve: fighting, fleeing, feeding and mating (a more polite synonym of the word "fucking").

Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. [1]
Nesting behavior refers to an instinct in animals during reproduction to prepare a place with optimal conditions for offspring. [1] The nesting place provides protection against predators and competitors that mean to exploit or kill offspring. [2] It also provides protection against the physical environment. [1]
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements.The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
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]
Post-copulatory female mimicry by the male offers an advantage by acting as a mate-guarding mechanism. If a second male arrives soon enough after the female copulates with the first male, the second male may be able to induce a second copulation which will compete with the first one.
