The Siamang (Symaphalangus syndactylus) is a species of large gibbon native to the Malay Peninsula and Sumatra. They are distinguishable by their large grayish-pink throat sac which they can inflate to the size of a grapefruit when vocalizing. That singing helps them defend their territory and socialize with other siamangs. They live in the rainforests and monsoon forests of Malaysia and Indonesia, usually remaining in the trees between eighty and a hundred feet high. They are the only gibbons with opposable thumbs and an opposable toe, which allows them to hold things in their hands or in their feet. They also have webbing between their second and third toe.
Siamangs have an upright standing height of 29.1”-35.4” (74-90 cm), head to rear length between 18.9”-23.6” (48-60 cm), and an estimated body width of 12.2”-14.6” (31-37 cm). The typical weight of the Siamang is in the range of 22-31 lb (10-14 kg). Siamangs have lifespans between 25-30 years in the wild and 30-43 years in captivity.
