In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
Necrophilia: This describes when an animal engages in a sexual act with a dead animal. It has been observed in mammals, birds, reptiles and frogs. [122] Bisexuality: This describes when an animal shows sexual behaviour towards both males and females. Extended female sexuality: This is when females mate with males outside of their conceptive period.
Sexual learning (a form of associative learning) occurs when an animal starts to associate bodily features, personality, contextual cues, and other stimuli with genitally-induced sexual pleasure. [ 14 ] [ 15 ] Once formed, these associations in turn impinge upon both sexual wanting and sexual liking.
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 ] Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization . [ 2 ]
Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. [6] [7] Sexual reproduction also occurs in some unicellular eukaryotes. [2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea.

Sexual coercion has many benefits to males allowing them to mate, but their strategies pose high cost for females. [17] This has been observed in vertebrates like green turtles. [ 19 ] The green turtles is an example of a species that does not receive any possible benefit from polyandry and only uses it to reduce the cost of mating. [ 19 ]
