By Allan Hall Cute as a button: Polar bear cub Anori explores her open-air enclosure at Wuppertal Zoo in Germany The half-sister of late celebrity polar bear Knut made her debut in Germany this week - and she may have even more star quality than him. Anori has the same father but a different mother to the troubled Knut who collapsed and died from a brain tumour aged just four a year ago. Unlike Knut, she was not abandoned at birth by her mother but appeared in public with her at Wuppertal Zoo. SCROLL DOWN FOR VIDEO Little adventurer: Anori is dwarfed by a log as she struggles to clamber over it Anori was born on January 4 to Knut's dad Lars and his new mate Vilma. She ventured forth to the adoration of the camera clicking crowds on Thursday. She frolicked, she tumbled, she made spectators gasp with delight and zoo director Ulrich Schürer said; 'It all went really well.' But he aims to protect Anori from the kind of frenzy that consumed Knut and turned him into a publicity addict who was only happy when he was performing. According to zoo officials, Anori opened her eyes one month after the birth, and took her first steps after two months. Playtime: Anori frolics with her mother.

Anori was one of two cubs born in the litter, but the second one died a week later. But while the crowds enjoyed the bear's confident show, Mr Schürer warned that the threats to the species must not be forgotten. Sniffing her way: Little Anori inspects a rock Peek-a-boo!

Rejected by his mother at birth, Knut was raised by a handler at Berlin Zoo, Germany, and thanks to his super-cute looks became a worldwide sensation. He sadly passed away from a brain tumour last year, aged just four 'I hope that the people who will see it, will also remember that polar bears are an endangered species,' he said. 'If global warming continues, then there soon won't be any more polar bears because their livelihood will be destroyed.' Anori won't be markted like Knut - he brought in six million pounds for Berlin Zoo - and her exposure to the public will be limited during her formative months. source:dailymail
