The Abbot’s gray gibbon^[1], also known as a western gray gibbon, is an acrobatic primate of the gibbons’ family, Hylobatidae. Abbott’s gray gibbons are very small and light.

• These species have a small, round head, long arms, and a slender, short body. Like all apes, they have no tail.
• They are covered in dense light to very dark brown (or black) fur over most of their body (except for the face, palms, fingers, forearms, and armpits).
• Abbott’s gray gibbons have hairless faces with small nostrils, dark eyes, and jet-black fur.
• Their hands are very similar to ours; they have 4 long fingers and a small opposable thumb. Their feet have five toes, including an opposable big toe.

The Abbott’s gray gibbon was named after zoologist William Louis Abbott. He discovered the species in 1905^[2] in the Southeast Asian island of Borneo.

• Depending on gender, Abbott’s gray gibbons weigh 6 to 9 kilograms.
• They have extra-long arms and powerful legs for swinging and leaping from tree to tree.
• They are better at walking on two feet than any other ape or monkey.
• This species is endangered due to heavy deforestation in Borneo and increased forest fires.
