Microcebus lehilahytsara is little bigger than a mouse. Two new species of lemur have been discovered on the island of Madagascar. The first new breed is a giant mouse lemur the size of a grey squirrel with a bushy tale, called a Mirza zaza. The second is a giant mouse lemur called Microcebus lehilahytsara. It’s small enough to fit in your hand, with round ears and a stripe on its nose. Lemurs are only found in the wild on Madagascar. The island broke off from mainland Africa 165 million years ago and is home to many rare animals. Lemurs are the closest living relation to our ancient primate ancestors who lived about 55 million years ago.
