Millie, a fatigued mom of an toddler, was prepared for a nap.
So she grabbed her child, flipped it round, threw it on her stomach and began grooming its tail — a soothing habits.
Millie, a sea otter, is rearing what could possibly be the Aquarium of the Pacific’s first orphaned pup to return to the wild. As a surrogate mother, she’s educating her adopted child the whole lot she must know to fend for herself — within the hopes she will be able to hack it within the ocean in a couple of months.
“It’s all instinctual, and he or she’s doing it manner higher than any human ever can,” stated Megan Smylie, sea otter program supervisor on the Lengthy Seaside aquarium.
Their pairing isn’t all about cuddles and leisure. Simply earlier than Millie determined it was nap time, the pup referred to as 968 was practising manipulating a crab shell, one of many expertise she’d have to survive within the ocean. She’d additionally have to grasp foraging for meals and grooming her thick, insulating coat.

Local weather warriors in limbo
In contrast to seals and sea lions, otters must be taught fundamental survival expertise. And, conservationists say, their survival is a excessive precedence.
They’re so essential to sustaining a wholesome coastal ecosystem that they’re usually referred to as “local weather warriors.” Otters chow down on urchins, which voraciously devour kelp. When urchins are saved in verify, kelp forests flourish — sequestering carbon and offering meals and shelter for fish, shellfish and different life.
As soon as considered extinct, southern sea otters’ rebounding inhabitants has stalled, stymied by shark bites and parasites. They dive, hunt and float from south of San Francisco to simply north of Santa Barbara, a fraction of their historic vary, making them susceptible to localized catastrophes resembling oil spills.
There are actually about 3,000 southern sea otters. That’s heartening relative to the whole within the late Thirties — about 50 — however a far cry from their 150,000-300,000 peak within the early 18th century. Looking almost eradicated them, whereas protections helped them claw again. The inhabitants has stabilized during the last 5 years.
Typically child sea otters get separated from their moms, who may fall sufferer to a predator or get swept away throughout a storm. In the event that they aren’t reunited or rescued by folks, the outlook isn’t good; most child otters can’t survive lengthy alone.
With the latest rollout of its otter surrogacy program, the Aquarium of the Pacific joined the Monterey Bay Aquarium’s efforts and has roughly doubled the capability in California to rehabilitate orphan otters utilizing adoptive mothers — a technique analysis has proven offers the otters the very best probability (about 75%) of being wild once more.
It’s a promising enlargement, however nonetheless falls in need of the necessity. Most years, extra otters strand than the Lengthy Seaside and Monterey services can accommodate, in response to staffers.
“So rising this program goes to be a fairly excessive precedence for those that are invested in otter conservation,” Smylie stated.

Hi there 968
Towards the tip of January, a passerby discovered 968 stranded north of Santa Cruz. Typically an otter mother might be heard calling out for her child someplace close by. However the pup was on their own.
She was about 8 weeks outdated, and nonetheless depending on her mom for survival. (Otter dads are usually not within the image.)
So she was taken to the Monterey Bay Aquarium, the place all sea otter pups stranded in California go by. Her quantity denotes that she’s the 968th otter to enter the aquarium’s rehabilitation program.
Pups aren’t simply tossed again into the surf; they have to undergo rehabilitation to discover ways to be an otter.
So started her lengthy, and nonetheless unsure, path again to the chilly coastal waters of Central California.
Educating an otter find out how to be an otter
The Aquarium of the Pacific’s foray into otter surrogacy is an outgrowth of the pioneering efforts of the Monterey Bay Aquarium, which began rescuing otter pups within the mid-Nineteen Eighties, even earlier than it formally opened its doorways.
The surrogacy idea emerged early on, stated Jessica Fujii, supervisor of the Monterey Bay Aquarium’s sea otter program. Within the wild, by their analysis program, workers “noticed adoptions occurring naturally; it wasn’t frequent, nevertheless it had been seen,” she stated. “So there was this thought that the sturdy maternal instincts that sea otters have may translate to the surrogacy in care.”
However an early try, in 1987, wasn’t profitable. So for a time staffers tried to behave because the pup’s mother, even swimming and diving alongside it in an enormous tidepool close to the aquarium to show it to forage.
To maintain rehabilitating otters from turning into too snug with people, aquarium workers members resembling Brett Lengthy watch them remotely.

Whereas otters raised this manner have been in a position to hunt, they didn’t at all times socialize correctly, stated Brett Lengthy, senior director of birds and mammals at Aquarium of the Pacific. Many have been too snug with folks.
“We’re superb at preserving them alive and superb at preserving them wholesome,” Lengthy stated. “What we’re not superb at is educating them find out how to be an otter again on the market.”
Then, in 2001, the Monterey Bay Aquarium paired an orphaned pup with Toola, a stranded feminine otter who’d had a stillborn. The pair bonded.
From there, the aquarium tried pairing orphans with otters that hadn’t been “primed” by a latest start. Extra success.
They continued refining the strategies, distancing people from the caretaking course of as a lot as doable. Caretakers put on disguises paying homage to Darth Vader’s getup throughout feedings — so that they’re not acknowledged as folks. Panels are put round their swimming pools to dam the sight of people, and the otters are monitored remotely. Releasable otters are additionally by no means positioned in aquarium shows the place throngs of tourists can “ooh” and “ahh” at them.
Researchers beforehand thought “expertise and information of the ocean was crucial half” of the rearing course of, Fujii defined. “And what we since realized is that actually that social side and that type of identification as, ‘You’re an otter,’ was actually key.”
Over 20 years, 70 pups have handed by the Monterey aquarium’s surrogacy program. Ten mature feminine otters did their half as adoptive mothers. A research discovered the rewilded otters contributed to inhabitants progress in an estuary referred to as Elkhorn Slough. In 2002, when the aquarium started its releases, there have been solely about 20 otters within the estuary. By 2016, there have been greater than 100.
In late February 2020, the Lengthy Seaside aquarium introduced it was becoming a member of the surrogacy program as a associate and welcoming Millie, who’s now 7. The pandemic across the nook delayed this system’s rollout, and it wasn’t till September 2023 that the allow was accredited. However they nonetheless needed to watch for a stranded otter to place Millie’s surrogacy expertise to the take a look at.
A protracted highway dwelling
After a three-week stabilization interval, 968 was pushed from Monterey to Lengthy Seaside. In the course of the roughly six-hour drive, she had ice to munch on and funky air piped in.
When 968 met Millie in February, it wasn’t familial love at first sight — at the least on the pup’s finish.
She stranded later than most pups, which means she might have had some reminiscence of her organic mother, specialists stated.
“And so the primary time it met Millie, it was like, ‘You’re not my mother.’ And Millie, thankfully, was simply affected person and was, like, ‘Hey, I’m within the pool. I’m hanging out,’” Lengthy stated.
A really chill stepmom tactic.
However by the sixth day, issues have been much less chill. If a bond doesn’t kind in seven days, then it possible by no means will, Lengthy stated.
Aquarium personnel would get excited each time the pup swam nearer to Millie. When the 2 otters lastly united, after almost seven days, cheers erupted from the workplace the place they watched the occasions unfold on a livestream.

“I don’t know that that’s going to fade,” Lengthy stated of the collective enthusiasm. “There’s some invested folks on this challenge, [and] this has turn out to be a very fashionable nook of our administration.”
Now Millie and the pup are inseparable. In late March, 968 rested on Millie’s stomach the very best she may — the pup had grown to round 18 kilos, from about 11 when she arrived in Lengthy Seaside.
After a calming nap within the solar, they made their solution to the opposite aspect of the pool. The pup, now about 4½ months outdated, performed with a bit of a crab shell as Millie relaxed on a platform. Quickly the hyper child scampered up subsequent to mother in what gave the impression to be the otter model of “Ma, take a look at me!” Based on Lengthy, the pup was in a stage akin to the horrible twos.
Millie, in a way, is giving again to this system. She was raised by surrogacy herself and for some time did simply tremendous within the wild — till folks began feeding her, which is illegitimate, specialists stated.
When she was about 2½ years outdated, she began leaping on kayaks, and federal wildlife officers ordered her out of the water. When Millie was fished out, it turned out she was pregnant. (Millie’s story is paying homage to the surfboard-stealing otter that turned a nationwide sensation over the summer time. That otter, dubbed 841, gave start within the wild shortly after her antics grabbed headlines.)
Millie raised her pup utilizing the surrogacy program protocols, and it was finally launched. It seems her maternal intuition hasn’t pale.

The take a look at
The launch of 968 will rely on whether or not she will be able to attain sure developmental milestones. She has to point out she will be able to take care of her luxurious fur; crack open clams, mussels and different meals; socialize moderately properly with different otters and keep away from people.
She’ll separate from Millie when she’s about 6 months outdated — the age pups usually depart “dwelling” — and head again to the Monterey aquarium the place she’ll hang around with otters nearer to her personal age. There, she’ll additionally get the chance to hunt reside prey.
If all goes properly and he or she passes a ultimate well being examination, she’ll return to her native waters. She’ll be implanted with a tracker and rigorously monitored for 2 weeks. After that interval, her survival chances are high pretty much as good as any otter.
Sadly, you possibly can’t wave to 968.
As a result of the surrogacy program hinges on preserving people away, guests on the Lengthy Seaside and Monterey aquariums received’t have the ability to see the otters. The rearing swimming pools on the Aquarium of the Pacific are tucked behind a medical heart and a marine mammal safety legislation prohibits livestreaming their actions to the general public.
Nevertheless, the Lengthy Seaside aquarium has launched an exhibit explaining this system. And, sure, it does embody lovely video of child otters.
