London Zoo has been urged to review its events programme after concerns were raised about their impact on animal welfare.
Weighing in at at a tiny 37 grams when hatched, the first of the young crocodiles emerged from its egg in June.
London Zoo has had a surprise new addition in the form of their first ever baby sloth -but keepers didn't even know the parents had mated.
London Zoo has released hidden camera footage of three newborn tiger cubs. The incredibly rare Sumatran tigers were born at the beginning of last month to mother Melati. The cubs remain with their mother inside a special 'cubbing den' and Melati will only occasionally venture away for food.
The Zoo has not yet found out what sex the cubs are as they haven't left their mother's side.
Zookeeper Teague Stubbington said 'We couldn't be more delighted with our new arrivals, and with how Melati is responding to her three cubs'
This lemur clearly decided to get involved in the recent trend for selfies before he took this series of shots.
The 12-year-old ring tail lemur, named Bekily, grabbed the camera from London Zoo keeper Tegan McPhail and seemed to enjoy his moment in the spotlight.
Ms McPhail said: "We’re always taking quick pictures of the animals we look after – as with workmates this cute, it’s hard to resist - but Bekily definitely wanted to get in on the action himself this time."
The zoo in Regent's Park is offering people the chance to win a share of £10,000 by entering its animal photography competition.
The winning pictures will be displayed at a zoo exhibition this autumn.
