A female giant panda cub born at Tokyo's Ueno Zoological Gardens has survived the initial fragile period after birth, turning 1 month old on July 12.
"With pandas, the 1-month-period immediately after birth is an unstable time, so I think the cub has successfully managed to overcome the difficult first stage of life," zoo head Yutaka Fukuda said in a news conference the same day.
The young cub, born to giant panda Shin Shin, now weighs 1,147.8 grams -- approximately eight times her weight at birth -- and is about twice as long as when she was born, at a length of 29.5 centimeters, as of July 12. The black-and-white patches on the panda's body are clear, and it is thought that her eyes will open in about 10 to 20 days' time.
Shin Shin, aged 12, has been raising her cub in a typical manner over the past few weeks, according to the zoo.
