(CNN) -- Seven months of pregnancy down, 15 to go. That's the good news the Oklahoma City Zoo shared publicly after an ultrasound and other tests confirmed their 18-year-old Asian elephant, Ahsa, is pregnant. The average gestation for elephants is 22 months, the zoo wrote in a press release. "It looks like a unicorn," posted one of the zoo's Facebook fans after viewing the photo. "So much better than a unicorn," the zoo replied. "How wonderful!" posted fan Amanda Lenzo. "I'm glad I'm not an elephant. I'm five months with my first. I am impatient with my nine months. I couldn't imagine 22 months. I think i know what i will be planning for my daughter's first bday....maybe a zoo trip." This is the the second pregnancy for Asha. Her first calf, Malee, was born two years ago, the zoo reported. The father is a 43-year-old named Rex, who is from the African Lion Safari in Cambridge, Ontario. He has sired five offspring previously, according to the Oklahoma City Zoo. "Asha has proved to be a great mother -- she's diplomatic, setting boundaries when she should while giving Malee the appropriate freedom to explore," said Nick Newby, the zoo's pachyderm supervisor.
