comments,

• Hylobates agilis certainly has impressive agility.""But have you heard it sing?
• Could this display be enough to earn a last-minute call-up to today\s artistic team all-round Olympics gymnastics final?""We must be out of our tree
• It\s a long way from the middle of the jungle to the world\s number one concert venue.""Do you think this gibbon has got a map?
• We\re not sure such foolhardy animal antics are recommended - this species is endangered.""You\ll find them misbehaving on the third largest island in the world
