A three-month-old London Zoo gorilla nicknamed Tiny has taken his first steps. Zookeepers were there to capture the moment the little Western lowland gorilla climbed off his mother for the first time and began stumbling around his enclosure. Tiny, who is getting his first teeth through, is the first gorilla born at the zoo for 23 years. The 2.5kg ape is unlikely to remain tiny. Male lowland gorillas typically grow to weigh between 136-181kg.
