Teo (born 16th October 2011, age 7) is a male golden-cheeked gibbon.

He was born at Monkey World as the third child and second son of Peanut and Pung-Yo, who previously had Tien in 2006 and Tia Nang in 2009.

In 2016, Teo was moved from his parents enclosure and moved in with two other male golden-cheeked gibbons named Zak and Mikado as he had reached the age that golden-cheeked gibbons leave their families. That same year, Teo became an uncle after Tien and Kim had a son. Sadly, the infant died shortly after birth.

Currently Teo stays with Zak following Mikado's move to a French zoo with Tia Nang.
