The cubs, two boys and a girl, arrived in July. According to the Daily Mail newspaper, only one out of every 10,000 Bengal tigers have the dramatic coloring.

这几只7月出生的幼崽中，2只为雄性，一只为雌性。根据《每日邮报》消息称，每10000只孟加拉虎中才有一只具有如此特别的白色斑纹。

The zoo has staged a contest to name one of the boys. Zoo employees will name the others.

动物园开展了一场为雌性幼崽命名的比赛。动物园员工将为其他的幼崽命名。

The cubs will be baptized this week, the paper reports. Male Bengal tigers can grow to 500 pounds, females up to 375 pounds, and they can measure eight feet long.

成年雄性孟加拉虎体重可达500磅，而雌性虎则可达375磅，长约8英尺。

White tigers don't live long in the wild, in part because their white coats stand out. In the past century, only 12 have been seen in the wild, according to the Daily Mail.

白色斑纹的孟加拉虎不能在野外生活过久，一部分是因为他们的白色斑纹太过显眼。据每日邮报称，在过去的几个世纪里，野外仅存的白色斑纹孟加拉虎为12只。

At the zoo, their life expectancy is close to 20 years. Here, one of the cubs cuddles with mom.

在动物园中生活的它们寿命可达20年。
