SIAMANGS
Symphalangus syndactylus
DESCRIPTION
Siamangs (Symphalangus syndactylus) are large gibbons known for their distinctive throat pouch, which they use to produce loud calls that can be heard over long distances. They have long arms and a black fur coat, with some individuals displaying a lighter coloration. These primates are highly social and live in family groups, often engaging in acrobatic displays as they move through the trees of their forest habitats.
FUN FACTS
- Siamangs are known for their impressive vocal abilities, with their throat pouch allowing them to produce deep, resonant calls that can travel over 2 miles in the forest
- They are also one of the largest species of gibbons, and their long arms and strong hands make them exceptional climbers and swingers in the treetops.|Siamangs are monogamous and form strong pair bonds, often seen grooming each other and caring for their young together
- Their social structure is unique among gibbons, as they often engage in synchronized singing, which strengthens their family bonds and establishes territory
