Before you finish your Monday morning cup of coffee, I would like you to go and book a flight to either Malaysia, Thailand or Sumatra where you will have the opportunity to observe a bizarre primate, simply known as the Siamang. This particular animal is the largest of the Gibbon family and just happens to be the largest Lesser Ape, roaming the planet. Basically, all this just means that the Siamang is a big primate. How big? Well, you will have to keep reading to find out. Actually, let’s find out right now.
How Big is the Siamang?
This Gibbon species typically reaches 1 m (3′) in height and will weigh up to 14 kg (30.8 lbs), so they are large but not World Record Holders by any means. Although, they are still very distinctive for two interesting reasons. The first has to do with their toes. Let’s just say they would have a tough time playing “This Little Piggy” since two of their toes are partially joined by a thin membrane. Yes, this particular Ape actually has webbed feet. The second distinguishing feature is the large throat pouch found on both males and females. The Siamang is able to inflate the sac to the size of a grapefruit. Not only is it a great party trick but it also helps amplify their sounds making their communication louder and more aggressive.
Family Protection Plan
This increase in amplification comes in handy considering the Siamang are incredibly territorial and typically will spend a good portion of their day singing to ensure no intruders enter their home range. This Gibbon species typically forms small family groups consisting of a mated pair and up to 4 young, so I guess they are defending their territory in order to protect their family. Aren’t they good parents?
A Resting Ape
Although they are fierce when it comes to defending their territory, the Siamang is actually quite laid back, as they spend 50% of their waking hours just relaxing. The other half of their day is composed of feeding, social activities and moving around. I am a little envious that the Siamang only has to work for half a day but then again, they do have webbed feet and a weird throat pouch, so perhaps they were due to catch a break from Mother Nature.
