The Dallas Zoo announced on Thursday the birth of twin Sumatran tiger cubs.
Sukacita, also known as Suki, delivered one male and one female cub on February 22. Each weighed about 2.5 pounds at birth and has grown stronger under the mother’s care, the zoo reported on social media.
“For now, the cubs are staying behind the scenes, giving them time to bond with mom and build the strength they’ll need before exploring their habitat,” the zoo’s Instagram post said.
Fewer than 600 Sumatran tigers remain in the wild, making the species critically endangered, according to the zoo.
“The birth of these cubs represents an important contribution to the long-term survival of the species and global conservation efforts,” the zoo said in a statement, per CBS News Texas.
The zoo launched a naming contest fundraiser for the female cub. Supporters can donate to vote for one of three options: Alya (pronounced ah-lee-ya), meaning “sky” or “heaven” in Arabic; Merapi, the name of the most active volcano in Sumatra; or Rina, in honor of Rina PA, a ranger in the Sumatran Ranger Project.
All proceeds support animal care and conservation for endangered species. The contest runs through April 20.
