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.

Sexual dimorphism is the condition where sexes of the same species exhibit different morphological characteristics, including characteristics not directly involved in reproduction. [1] The condition occurs in most dioecious species, which consist of most animals and some plants.

[3] Guinean baboons have a red tone to their fur, and are sometimes referred to as the red baboon. They lack hair on their hindquarters, and their faces are black with yellow-brown sideburns.
The mandrill (Mandrillus sphinx) is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. It is the largest monkey in the world.
Primates exhibit the highest levels of sexual dimorphism amongst mammals, [2] therefore the maximum body dimensions included in this list generally refer to male specimens. Mandrills and baboons are monkeys; the rest of the species on this list are apes.
Sexual swelling, sexual skin, or anogenital tumescence refers to localized engorgement of the anus and vulva region of some female primates that vary in size over the course of the menstrual cycle. [ 1 ] [ 2 ] [ 3 ] Thought to be an honest signal of fertility , [ 4 ] male primates are attracted to these swellings; preferring, and competing for ...
Hamadryas baboons also eat insects, spiders, worms, scorpions, reptiles, birds, and small mammals, including antelope. [12] The baboon's drinking activities also depend on the season. During the wet seasons, the baboon do not have to go far to find pools of water. During the dry seasons, they frequent up to three permanent waterholes. [12]
