Did you know that Sun Wukong is based on a real species of monkey? In chapter one, the patriarch Subhuti tells Sun: “Though your features are not the most attractive, you do resemble a pignolia-eating macaque [husun, 猢猻].”  The master dismisses the Hu (猢) character for linguistic reasons, and he drops the animal radical (犭) for religious reasons, leaving Sun (孫, “grandson”) as Monkey’s surname. Possibly quoting an earlier source, the noted Ming physician Li Shizhen (1518-1593) explains the meaning of husun and associates it with a particular genus: “Since a macaque resembles a Hu-barbarian [胡], he is also called hu-sun, ‘grandson of a barbarian’” (Gulik, 1967, p. 35). There are several species of macaque native to China, but anthropologist Frances D. Burton (2005) believes the Rhesus macaque (Macaca mulatta) is the best fit:
Monkey goes bare-headed and wears a red dress, with a yellow sash, and black shoes. This is a fitting description of M. mulatta, whose reddish fur on shoulders and back yields to lighter, more yellowish fur on the abdomen, and whose feet and hands are black. The ‘pouch’ to which the Monkey King himself refers [to in the novel] would likely be the cheek-pouches common in macaques, but not gibbons or leaf-eating monkeys.
One of Monkey King’s epithets is ‘Fiery Eyes”. His red eyes–a characteristic he shares with the actual red-rimmed eyes of M. mulatta [Fig.1][…]–resulted from his punishment in a crucible. […] He is also a ‘red-bottomed horse ape’, which suggests M. thibetana or, again M. mulatta, both of which are large animals, with pronounced redness on the bottom, especially during reproductive phases (p. 148).

In chapter two, a monster describes Monkey as being “not [even] four feet tall” (Wu & Yu, 2012, p. 128). Rhesus males measure on average 1.74 feet (Lang, 2005). But I imagine these measurements were taken while they were in a quadrupedal posture (on all fours), which would make them taller if they stood.
I think all of this information is important as modern day depictions of Sun portray him as a man (or the size of a man) or a hulking brute with huge muscles. Such depictions are extremely inaccurate. He is a short monkey, plain and simple. His great strength, martial arts skill, and magical abilities make him a formidable warrior, not his size. I think the Japanese produced the most accurate renderings of monkey. The work of Yoshitoshi (1839-1892) is a good example (Fig. 2).
Readers will no doubt recall the golden fillet that Sun Wukong unwillingly wears on his crown. Humanoid depictions of the character show the band sitting on the frontal and parietal areas of the skull. But since Rhesus macaques have a much smaller brain pan, the circlet would have to wrap around the top of the eye orbits and the back of the occipital bone in order to be effective (fig. 1). It would set just above the eyelids (fig. 2).
