Fertilisation
Fertilisation (also known as conception, fecundation and syngamy) is the fusion of gametes to initiate the development of a new individual organism. In animals, the process involves the fusion of an ovum with a sperm, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilisation, or outside (external fertilisation). The entire process of development of new individuals is called reproduction.

Animal sexual behavior
Animal sexual behaviour takes many different forms, even within the same species. Among animals, researchers have observed monogamy, promiscuity, sex between species, sexual arousal from objects or places, sex apparently via duress or coercion, copulation with dead animals, homosexual sexual behaviour, heterosexual, bisexual sexual behaviour, situational sexual behaviour, and a range of other practices.
