Infants in bonobo societies are often involved in sexual behaviour. [78] Immature male bonobos have been recorded initiating genital play with both adolescent and mature female bonobos. Copulation-like contact between immature bonobo males and mature female bonobos increases with age and continues until the male bonobo has reached juvenile age.
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes).

Extant primates exhibit a broad range of variation in sexual size dimorphism (SSD), or sexual divergence in body size. [4] It ranges from species such as gibbons and strepsirrhines (including Madagascar's lemurs) in which males and females have almost the same body sizes to species such as chimpanzees and bonobos in which males' body sizes are larger than females' body sizes.
Giraffes are “super queer,” at least according to one scientist in a new documentary about the diversity of animal sexuality. “Queer Planet,” which debuts June 6 on Peacock, NBC’s ...
The term is also applied, usually informally, to homosexual activity between two males among bonobos; same-sex genital-genital rubbing is used in bonobo society to cement bonds, reduce conflict, and express communal excitement over food. [12] Several whale species also engage in penis fencing. [13]
Anatomical differences between the common chimpanzee and the bonobo are slight. Both are omnivorous adapted to a mainly frugivorous diet. [50] [51] Yet sexual and social behaviours are markedly different. The common chimpanzee has a troop culture based on beta males led by an alpha male, and highly complex social

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 ...
