Siamangs are the largest of the gibbons and use their long arms to swing through their native forests. Siamangs have long and thick black coats that cover nearly all of their body. Most notably, siamangs have a large gray or pink throat sac that is used for communication. This sac inflates to make noises that can sound like a loud boom or a bark. Siamangs use these sounds to defend their territory and for other communicative activities.
Palm oil is an edible oil that is found in about half of the products consumers purchase. That’s right, half. It’s used in making candy, soap, cosmetics, pet food, and even toilet paper. Because of high demand, ongoing palm oil production deforests more and more areas in Southeast Asia and other tropical regions. This deforestation means less habitat available to wildlife, resulting in species, including the Siamang, being pushed toward extinction.
