TOKYO, Nov. 13 (Xinhua) -- Twin cubs of giant panda Rauhin at the Adventure World amusement park in Wakayama Prefecture of Japan in September were named Meihin and Eihin on Thursday.
Meihin, the female cub, was born in early morning of Sept. 13 and Eihin, the male cub, about 70 minutes later. They weighed about 194 grams and about 116 grams at the time of their births.
The twins now weigh over 2 kilograms each and are opening their eyes, Kyodo News Agency quoted park officials as saying.
Rauhin, born in September 2000 at the park in the town of Shirahama, became the first Japanese-born panda to become a mother. She got pregnant through natural mating in April.
