The siamang is an endangered, black-furred gibbon native to Southeast Asian forests that is notably the largest gibbon species, sometimes reaching twice the size of other gibbons. Understanding and protecting siamangs matters because they are at risk of extinction and represent a unique primate lineage with a fossil history stretching back millions of years.

Two features distinguish the siamang from other gibbons. First, two digits on each foot—the second and third toes—are partially joined by a membrane, hence the specific name syndactylus, from the Ancient Greek σύν, sun-, "with" + δάκτυλος, daktulos, "finger". Second, a large gular sac (throat pouch), found in both males and females of the species, can be inflated to the size of the siamang's head, allowing it to make resonating calls.
