Sharjah24 – Reuters: These tiny twin monkeys made their public debut at a British zoo earlier in the week.

The baby eastern pygmy marmosets monkeys, now about 5 centimetres in length an weighing around 10 grams, were born on September 7 to parents Zoe and Baldrick.

"It's almost unbelievable just how small the babies are when they are first bom," Holly Webb, a primate keeper at Chester Zoo said. "They are no bigger than a ping pong ball."

Marmosets are some of the smallest monkey species in the world.
