Last week, photographer Mark Eastment got some great pictures of the Bristol Zoo's Asiatic Lion cubs in their outdoor enclosure. The cubs, born Christmas Eve, are now just over 3 months old and as playful as ever. Asiatic Lions are critically endangered in the wild – with only about 300 remaining in the Gir Forest Sanctuary in Northern India. They were once widespread throughout Northern India and Pakistan, but hunting and habitat destruction has reduced their numbers drastically.
