He is the first gibbon introduced into the research institute and has been used in various research projects, such as a biped walking experiment [1]. He has since been named Mamy, and many elderly researchers remember him. He had two children with Ibu, born in 1998 and 1999. People often ask, "Why is it called Mamy despite the fact that it is a father?" However, the origin of his name is unclear.
As of 2011, his weighs ~6.4 kg and has thin, shiny, straight hair. The hair is in the gradation of dark brown and yellowish-brown; it is a lighter brown on the waist section and darker on its thoracic and abdominal parts and on the backs of his hands and legs. A feathering of his eyebrows, whiskers, and testis are white.His ears are round, and it has moist earwax. The second and third toes of both feet are webbed. All of his canines were reportedly cut down immediately after he became an adult. When he became sick in 2008, his left testis was swollen. Since then, the testis has atrophied. There is a 2-cm long keloid on his left knee. The first joint of the middle finger of his right hand is immobile. The genotype of his alcohol decomposability is low.
The individual has strong likes and dislikes regarding others. When he is relaxed, however, he plays well with others.
