Talk about big news: For the first time in the Columbus Zoo and Aquarium's history, two Asian elephants are pregnant at the same time — and one is due any day now.
Why it matters: The species is endangered, and its population in accredited zoos is currently unsustainable due to dwindling numbers and a lack of genetic diversity, according to the Association of Zoos and Aquariums (AZA).
- The calves' father — Sabu, from the Cincinnati Zoo, who lived here temporarily — has no living offspring, so the births will bolster the gene pool.
The big picture: The news comes as some zoos are moving away from keeping elephants amid increasing care standards, which require lots of space and expense.
- Others, like Columbus, are investing more by expanding habitats, encouraging breeding, and working with global partners to conserve wild elephants.
- Advocates say keeping elephants is important for research and education. A 2023 AZA strategic plan calls for increased collaboration among zoos, including transferring animals for breeding.
Threat level: "If we don't do something as a group, we're not going to have elephants in 100 years," says Adam Felts, senior zoo curator and head of the AZA's Species Survival Plan.
- At last count, there were 157 Asian elephants in 27 AZA institutions.

Zoom in: Felts took Axios behind the scenes to meet 38-year-old matriarch Phoebe, who is expecting her sixth calf.
- She's "all business," with a big appetite. The 7,400-pound pachyderm calmly used her trunk to funnel biscuits into her mouth while a veterinarian scanned her with an ultrasound probe.
- Her calf is likely the size of a Great Dane. It's impossible to see the entire thing in one image, but vets can view ribs, a skull or a beating heart. All appear healthy.

Another elephant, 16-year-old Sunny, is due with her first calf between now and August, while Phoebe is due in the fall.
- Keepers hope the experienced mom will show Sunny the ropes. They're encouraged by her bond with Phoebe's 3-year-old calf, Frankie, who still lives at the zoo.
- The arrangement should mimic wild herd behaviors, in which females raise the young together and males are mostly solitary.

The intrigue: The new calves will make history in another way, as Columbus' first to be vaccinated for elephant endotheliotropic herpesvirus (EEHV).
- The devastating virus is the leading cause of death among AZA elephants, and calves are especially at risk. A vaccine became available last year.
What's next: Elephants are pregnant up to 22 months, so expect lots of fanfare when the 200-plus-pound bundles of joy finally arrive.
1 fun prenatal ritual: elephant yoga
Impress your friends with this fun fact: the Columbus Zoo's herd is trained in "elephant yoga."
How it works: The elephants follow a target and maneuver into various poses, such as stretching their feet and trunks, kneeling, and lying on the ground.

Between the lines: Keepers say practicing the moves keeps them limber and engaged.
- It also helps them learn to get into positions for routine health monitoring, such as blood draws, exams and ultrasounds.
😅 Alissa's thought bubble: I definitely couldn't move as gracefully during my pregnancy as 7,400-pound Phoebe does. Impressive.
