They're only the size of a golf ball but these new arrivals have given zoo keepers reason to celebrate

Chester Zoo is celebrating the arrival of two radiated tortoises, which are critically endangered.

The “golf ball-sized” hatchlings, which are usually found in the dry forests of southern and southwestern Madagascar, are the first of their kind to be bred at the zoo for seven years.

Conservationists at the zoo have been working to hatch the tortoises after seeing at first-hand the ongoing devastation to their forest home in Madagascar.
