Symphalangus Syndactylus, commonly known as the Siamang, is a type of ape that can be found in Southeast Asia. The Siamang is known for its unique physical characteristics such as the webbing of its fingers and toes, as well as its distinctive vocalizations which are used to communicate with other members of its group. Synonyms for the Siamang include the lar gibbon, the greater gibbon, and the black gibbon. These names all refer to the same species of ape, each with their own slight variations in behavior and physical traits. Despite their unique features, Siamangs are unfortunately endangered due to habitat loss and hunting for their meat and bones.
