FORT WORTH, Texas — There are fewer than 550 Malayan tigers in the world, and three new ones have just made an appearance at the Fort Worth Zoo.

The zoo introduced a new litter of female Malayan tiger cubs Thursday. The three cubs were born at the zoo on April 28 and have been living off-exhibit in a private den with their mother, who also gave birth to cubs here in 2000 and 2003.

This species had been categorized and exhibited as the Indochinese tiger until earlier this year when genetic testing showed the tigers were actually Malayan. The critically endangered Malayan tiger is one of six tiger species. There are only 490 adults in the wild, and 45 in American zoos.
