Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
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.

Sexual coercion among animals is the use of violence, threats, harassment, and other tactics to help them forcefully copulate. [1] Such behavior has been compared to sexual assault, including rape, among humans. [2] In nature, males and females usually differ in reproductive fitness optima. [3]
Homosexual behaviour is demonstrated by 120 known species of birds. [40] While an uptick in research on bird homosexuality – and animal homosexuality in general – has been coming out in recent years, it's common for some authors to labour in articulating the view any root cause or function of bird homosexuality is poorly understood.
Its use in animal studies has been controversial for two main reasons: animal sexuality and motivating factors have been and remain poorly understood, and the term has strong cultural implications in western society that are irrelevant for species other than humans. [12] Thus homosexual behavior has been given a number of terms over the years.
The reason why some researchers are skeptical about animals having a sense of humor is that it serves no evolutionary purpose. For humans, it's a bonding strategy. For humans, it's a bonding strategy.
Animal sexual behavior takes many different forms, even within the same species and the motivations for and implications of their behaviors have yet to be fully understood. Bagemihl's research shows that homosexual behavior, not necessarily sexual activity, has been documented in about 500 species as of 1999, ranging from primates to gut worms .
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances.
