Newly born Bennett’s wallaby twins (Macropus rufogriseus) peer out of the pocket of their mother at the Thoiry Zoo, 60 kilometers (38 miles) west of Paris, Friday, May 7, 2004. The rare birth, discovered a few days ago by animal caretakers, were born a few months ago and feed from their mother’s teats at the bottom of the pocket, developing inside it for a few months. As a single youth becomes independent at 9 or 10 months, the twins are due to get out within a month time. (AP Photo/Michel Euler)
