Five white tiger cubs were born on Friday at the Siberian Tiger Park in Harbin, the capital of northeast China's Heilongjiang Province.

The white tiger quintuplets, one male and four females, are healthy and weigh about 1.2 to 1.4 kilograms each, Liu Dan, the park's chief specialist, said Saturday.

"Usually, white tigers will give birth to two to four cubs at one time. It is rare to see healthy quintuplets," Liu said.

The white tiger is a subspecies of the endangered Bengal tiger. It is estimated that between 200 and 300 white tigers live in captivity in China.

The Siberian Tiger Park, the largest Siberian tiger breeding and field training center in China, was founded in 1986. There are more than 1,000 Siberian tigers in the center at present.
