Help name the Dallas Zoo's tiger cub

The Dallas Zoo has two new Sumatran tigers and wants you to help name one of them.

Driving the news: The cubs were born in February, weighing around 2.5 pounds. The female cub's name is up for a vote.

Zoom in: The options are:

• Rina, which honors a ranger in the Sumatran Ranger Project.
• Alya, which means "sky" or "heaven" in Arabic.
• Merapi, the most active volcano in Sumatra, Indonesia's largest island.

How it works: To vote on a name, donate to the zoo through April 20.

• The mother's name is Sukacita (or "Suki") and father's name is Kuasa, in case that helps inform your vote.

What's next: The zoo says the babies will remain behind the scenes with their mother for now, bonding and getting stronger before their public debut.

• The zoo will announce the male cub's name when it announces the results of the female's naming contest.
