Dallas Zoo’s Sumatran Tiger Cub Officially Named Rina After Public Voting Contest
The public has spoken, and one of Dallas Zoo’s newest residents finally has her name.
The zoo’s female Sumatran tiger cub, born Feb. 22, 2026, is officially named Rina. The name was selected through a donation-based public voting contest that gave animal lovers a direct role in the cub’s story while raising money for conservation. Voters chose from three name options, each rooted in Sumatran culture and wildlife protection.
Her brother, Serasi, was named separately by the zoo’s animal care team. Both names honor rangers with the Sumatran Ranger Project, an organization that works to protect the critically endangered species in its native Sumatra. Fewer than 600 Sumatran tigers remain in the wild, according to Dallas Zoo.
The Public Picks from Three Options
The zoo presented three choices for the female cub’s name:
- Rina — in honor of Rina PA, a ranger with the Sumatran Ranger Project
- Alya — meaning “sky” or “heaven” in Arabic
- Merapi — the name of the most active volcano in Sumatra
Rina won the contest. Proceeds from the donation-based voting support conservation efforts.
The zoo shared the winning name — along with another milestone for the cubs — on Instagram.
“Thanks to your incredible support, the votes are in and our female cub’s name is Rina. Her name honors Rina PA, a ranger with the @sumatranrangerproject. Her brother, Serasi, was named by our animal care team in tribute to a ranger from the same organization who dedicated his life to protecting wildlife in Sumatra before his passing. His courage and commitment now live on in this little cub,” the zoo wrote. “And there’s more exciting news… today, for the very first time, Rina and Serasi stepped onto their habitat! Rina is already showing off her confidence, venturing out with Suki and taking in the space, while Serasi is taking things a bit slower, easing into it and building confidence at his own pace. “
What Both Names Honor
While the public chose Rina’s name, the zoo’s animal care team selected Serasi’s. His name pays tribute to a ranger from the Sumatran Ranger Project who dedicated his life to protecting wildlife in Sumatra before his passing. The decision to name both cubs after rangers ties the zoo’s conservation breeding program to the front-line work of keeping Sumatran tigers alive in the wild.
The naming contest also served as a fundraiser. The donation-based voting model meant every vote doubled as a financial contribution to conservation efforts tied to the species.
Two Cubs, Two Distinct Personalities
The cubs’ mother, Sukacita — known as Suki — gave birth to the pair on Feb. 22. Each cub weighed approximately 2.5 pounds at birth.
On the same day the zoo revealed Rina’s name, it announced that both cubs had stepped onto their outdoor habitat for the first time — a second piece of major news packed into one announcement.
Their personalities are already taking shape. Rina is the bolder of the two, venturing away from her mother to explore the space with confidence. Serasi is more cautious, staying close to Suki and building comfort at his own pace. The contrast was clear from the moment they reached the outdoor habitat, with Rina leading the way and Serasi easing in gradually.
There is no fixed schedule for when visitors can see the cubs at Dallas Zoo. Rina and Serasi will rotate habitat time with the zoo’s adult tigers, and Suki will guide them as they explore. The zoo said the cubs will venture out when they feel comfortable and the weather allows, so guests may catch glimpses on any given visit.
Why These Cubs Matter for the Species
Sumatran tigers are critically endangered. With fewer than 600 left in the wild, according to Dallas Zoo, every birth in a managed population carries weight for the species’ long-term survival.
“The birth of these cubs represents an important contribution to the long-term survival of the species and global conservation efforts,” the zoo said.
Rina and Serasi are now part of that broader effort. Their names — chosen to honor rangers who protect wild tigers in Sumatra — connect the work happening at Dallas Zoo to conservation taking place thousands of miles away.
