@usct.dfw: Fort Worth Zoo's first Sumatran tiger cubs. Twin sisters Barani and Malu are the first Sumatran tiger cubs born at the Fort Worth Zoo. Born in July to Ndari and Rakan, they are now 12 weeks old and weigh about 20 pounds each. Barani's name means brave, while Malu's means reserved. Sumatran tigers are critically endangered, with fewer than 650 remaining in the wild. The zoo expects the cubs to make their public debut in the coming weeks. #FortWorth #FortWorthZoo #SumatranTigers #TigerCubs
