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.
She appeared in Life magazine, where she became famous for drinking straight gin, rearing a cat, and using Playgirl and a vacuum cleaner for sexual gratification. [2] [3] Subsequently, the Temerlins introduced her for the first time to a male chimpanzee. She was frightened and did not relate to him, let alone find him attractive.
However, selection for ornamentation within this species suggests that showy female traits can be selected through either female–female competition or male mate choice. [59] Since carotenoid-based ornamentation suggests mate quality, female two-spotted guppies that develop colorful orange bellies during breeding season are considered ...
Male chimpanzees hunt in groups more than females. Female chimpanzees tend to hunt solitarily. If a female chimpanzee were to participate in the hunting group and catch a Red Colobus, it would likely immediately be taken by an adult male. Female chimpanzees are estimated to hunt ≈ 10-15% of a community's vertebrates. [122]
Felines, especially domestic cats, are well known for having penile spines. Upon withdrawal of a cat's penis, the spines rake the walls of the female's vagina, which may serve as a trigger for ovulation. [4] [5] Many other felid species have penile spines, but they are relatively small in jaguars and pumas, and do not occur in margays. [6]
The clitoris (/ ˈ k l ɪ t ər ɪ s / ⓘ or / k l ɪ ˈ t ɔːr ɪ s / ⓘ; pl.: clitorises or clitorides) is a female sex organ present in mammals, ostriches and other amniotes.. Although the clitoris exists in all mammal species, [1] [2] [3] most studies deal with the human clitoris - few detailed studies of the anatomy of the clitoris in non-humans exist. [4]

Lordosis behavior (/ l ɔːr ˈ d oʊ s ɪ s / [1]), also known as mammalian lordosis (Greek lordōsis, from lordos "bent backward" [1]) or presenting, is the naturally occurring body posture for sexual receptivity to copulation present in females of most mammals including rodents, elephants, cats, and humans.
