A child with Sotos syndrome showing characteristic facial features Sotos syndrome in the hand, showing enlargement. This syndrome is characterized by overgrowth and advanced bone age. Affected individuals have dysmorphic features, with macrodolichocephaly, downslanting palpebral fissures and a pointed chin. The facial appearance is most notable ...
In disease states, maxillary prognathism is associated with Cornelia de Lange syndrome; [8] however, so-called false maxillary prognathism, or more accurately, retrognathism, where there is a lack of growth of the mandible, is by far a more common condition. [citation needed]
The large-headed capuchin (Sapajus apella macrocephalus) is a subspecies of the tufted capuchin monkey from South America. It is found in Bolivia , Brazil , Colombia , Ecuador and Peru . [ 2 ] It was formerly thought to be its own species ( S. macrocephalus ), but studies have found it to be a subspecies of the tufted capuchin.
The capuchin monkeys (/ ˈ k æ p j ʊ (t) ʃ ɪ n /) are New World monkeys of the subfamily Cebinae. They are readily identified as the "organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina.

The mandrill is the most sexually dimorphic primate, [22] and it is the largest monkey. [23] Females are less stocky and have shorter, flatter snouts. [ 19 ] Males have a 70–95 cm (28–37 in) head-body length and weigh 19–30 kg (42–66 lb) while females have a 55–70 cm (22–28 in) head-body length and weigh 10–15 kg (22–33 lb). [ 24 ]
(2005) [34] have proposed this is likely more a factor of a monkey's terrestrial habit: the more time a monkey spends on the ground, the more likely it is to profit from (and thus engage in) tool use. In captivity, the tufted capuchin has been seen to manufacture stone tools that produced simple flakes and cores.
The monkey's size differs depending on sex and species. Males from all species can range from 41 to 70 cm (16 to 28 inches) in head and body length, and in weight from 5.5 to 18 kg (12.13 to 39.7 lb). [6] Females can range from a weight of 2.4 to 13 kg (5.3 to 28.7 lb).
