Some animal rescues are more complicated than others—especially when the creature in peril is about to become a snack for a seagull on a remote Alaskan beach with polar bears lurking nearby. 

That was the sticky situation an orphaned Pacific walrus (a subspecies of Odobenus rosmarus) calf was in when two researchers found it on an island in the region of Point Lay, Alaska. U.S. Geological Survey (USGS) research walrus biologist Tony Fischbach and Ilisaġvik College student and Point Lay local Violet Anniskett stumbled upon the young male while investigating walrus carcasses on a remote beach. They found the orphan between the remains of two adult walruses, which was a first in Fischbach’s long experience working with walrus herds there. 

The researchers requested permission to rehabilitate the walrus from the local Inupiaq community and the U.S. Fish and Wildlife Service. Once the approval arrived, the next hurdle was getting the mammal to the Alaska SeaLife Center. The center is the only marine mammal rehabilitation facility in Alaska, and was over 800 miles away. As if things could get any more difficult, stormy weather left Anniskett, Fischbach, and the walrus stuck on the island for days. In the meantime, the researchers guided the calf to an abandoned building to shelter from predators.

“When we found him, a determined flock of gulls was intent on scavenging him. He was in immediate peril of suffering this fate had we not gotten approval to intervene. Two polar bears were also active on the island,” Fischbach said in a statement. 

“He bonded with us fast and wouldn’t sleep unless one of us were in the room. It was just us two for three days, stuck in a storm with the young walrus,” Anniskett added. 

The calf was finally transported to the local airport, and made it to Alaska SeaLife Center on September 14 after a flight and van ride. The 200 pound baby arrived dehydrated, but in good physical condition. They treated some superficial wounds, gave him fluids, and applied other stabilizing treatments. 

But the calf’s journey wasn’t over. In fact, orphaned Pacific walrus calves are one of the most specialized patients in marine mammal rehabilitation.That’s because in the wild, calves are very attached to their mothers, with whom they usually stay for one to two years. Close physical contact both with their mothers and others of their king is a crucial element in a calf’s early life. In the case of an orphaned calf, humans (who are authorized specialists) can act as surrogates, but it’s a tough babysitting job. Someone has to be around all the time to provide physical contact, social interaction, feeding support, and any veterinary care. 

“Caring for an orphaned walrus calf is truly a team effort and requires around the clock commitment,” said Jane Belovarac, an Alaska SeaLife Center wildlife response curator. “At least two staff members have been working shifts around the clock to stay with him and provide the care he needs. This means long days and some unusual sleeping schedules for our team.”

It also means that the calf becomes comfortable with humans and thus cannot return to the wild. Now in a new long term home (whose location hasn’t been announced yet), he will be an ambassador for his species by teaching people about Pacific walruses.

The 13,800-year-old archaeological site points to an ancient cultural connection spanning the Bering Land Bridge.

It takes a village to raise a child, and sometimes it takes more than one wildlife rehabilitation center to care for a bat. Even if the bat in question weighs only six grams (about two ounces). 

The recent rescue of the juvenile bat in Lancaster, Pennsylvania involved teamwork from the beginning. The “sky puppy” had been hanging on a local porch for two days. While that might not sound off, the bat’s exposure to the elements in a single location for that period of time made the situation an emergency, according to Raven Ridge Wildlife Center in southern Pennsylvania. 

Pennsylvania Bat Conservation and Rehabilitation contacted Raven Ridge, who sent a team member to get the bat. The winged mammal was very dehydrated and underweight. It was also unlike the bats that typically arrive at Raven Ridge. The team stabilized her, recontacted PA Bat Conservation and Rehabilitation, and the two organizations realized that they had a northern long-eared bat (Myotis septentrionalis) on their hands.  

“Sadly, northern long-eared bats are now critically endangered in North America, with their population dropping by as much as 97% to 100% because of white-nose syndrome,” Tracie Young, Raven Ridge Wildlife Center director, tells Popular Science. White-nose syndrome is a fungal disease that has killed millions of bats in the U.S. and Canada. 

“They are now protected at both the state and federal levels,” Young adds.

A Raven Ridge volunteer ultimately drove the youngster to the PA Bat Conservation and Rehabilitation facility about an hour away, where the team is expert in critically endangered bats. The bat was eventually returned to the wild, with a video featuring the little bat launching from a woman’s gloved hand into the night. 

“Even though this is just one bat, it was important to get this bat to the rehabber who specializes not only in bats but also in those in a critically endangered status,” Young adds. “The video shows her flying beautifully. This effort was a wonderful partnership between Raven Ridge Wildlife Center and PA Bat Conservation and Rehabilitation.”

Happy bat appreciation month!

Nothing is quite as joyful as watching a dog get caught up in a bout of “zoomies,” zipping around a living room or backyard in a burst of energy. But our canine pals aren’t the only animals subject to these hyperactive displays. 

Young condors can also engage in zoomies, as demonstrated in a recent Facebook post from the Ventana Wildlife Society in California. The video shows clips of two young California condors (Gymnogyps californianus), Chert and Pumice, seemingly having a blast in their release pen.

“We observe the zoomies in both captive and wild condors. It’s just a sudden expression of pure excitement for young condors and very fun to watch,” Joe Burnett, California Condor Recovery Program Manager at the wildlife society, tells Popular Science. “Zoomies come out of nowhere and they just can’t contain themselves and totally let loose. They hop, run in circles, or flap around, or all the above! It’s just pure fun!”

It’s not just about the fun, however. Zoomies allow the young condors to release energy and grow stronger, as well as help them figure out their wings, according to the team. 

The two zoomie condors are 1.5-year-old males who were raised in zoos before arriving at Ventana Wildlife Society’s San Simeon release pen in early September. It’s called a release pen because Chert, Pumice, and three other captive condors will be kept in the pen to acclimate until their release on October 24 at 10 a.m. The release will also be livestreamed. 

The quintet will become a part of the wild condor population of central California, which today includes 104 individuals. But it won’t be a total goodbye. Scientists will be able to keep an eye on Pumice and Chert’s locations via wing-mounted radio & GPS transmitters and ID tags. 

California condors are North America’s largest land bird. They measure 9.5 feet from wing tip to wing tip. But their size didn’t spare them from a precipitous population drop. In 1982 there were only 23 condors left in the world. All wild condors were captured and included in a captive breeding program. 

“Condor releases are critical to achieving our ultimate goal- to reestablish a self-sustaining condor population in the wild,” Burnett concludes. 

At the end of 2025, there were 607 California condors. We’d say Pumice and Chert earned their right to party.

An endangered mouse is slowly returning to the Golden State. Pacific pocket mice (Perognathus longimembris pacificus) are about as large as a human thumb and about as heavy as three pennies. Unsurprisingly, they are the smallest mammals in North America and are one of many pocket mouse subspecies. But they are also one of the most endangered. 

Pacific pocket mice have lived in and around Los Angeles and San Diego but before 1993, the species was believed to be extinct. When a small population was found in Orange County,  the tiny rodent was listed as endangered. 

Today, there are only three original populations in the wild, but groups are being reintroduced into the wild. The San Diego Zoo Wildlife Alliance and their partners recently established their third reintroduced population of Pacific pocket mice at North San Mateo, a training area within Marine Corps Base Camp Pendleton.

“This spring, we provided 50 mice to USGS [United States Geographical Survey] to establish a third reintroduced population at North San Mateo, and we’re very encouraged that reproduction has already been documented there,” Debra Shier, associate director of recovery ecology for San Diego Zoo Wildlife Alliance, tells Popular Science. 

The two other reintroduced populations are also doing well. They are the Water Tank population in Laguna Coast Wilderness Park and the Wire Mountain population on Marine Corps Base Camp Pendleton. Mice there are reproducing, and the Water Tank population has a high to very high density. Additionally, the Wire Mountain population has a medium to high density, according to Shier. 

The Pacific pocket mouse’s recovery is good news for the subspecies, but also for their ecosystem. Their burrows contribute to improving soil hydrology and nutrient cycling and also shelter other species, Shier added in a statement. An additional population helps return these crucial ecological functions to their native coastal ecosystems. 

Since the start of its Pacific Pocket Mouse Conservation Program in 2006, the San Diego Zoo Wildlife Alliance has released over 500 of these tiny mammals into the wild, adding them to both new and established populations.  

“We’re now beginning to allow the established populations to expand beyond their original fenced release areas. That’s especially important this year because of the potential for heavy winter rains associated with the forecasted El Niño,” Shier says. “We’ve found that high winter precipitation can be associated with lower overwinter survival, so allowing mice to spread out and settle in a larger area may help make these populations more resilient.”

The greatest threat to Pacific pocket mice is the loss and fragmentation of their specialized coastal habitat. Habitat loss diminishes their range and makes them vulnerable to inbreeding. 

“So, recovery isn’t simply about breeding more mice,” Shier points out. “We need to protect and restore suitable habitat, establish additional populations, and maintain genetic diversity across those populations.”

As the summer drew to a close, aerial surveyors with the New England Aquarium saw more than 2,000 animals across 15 different marine species in the Northeast Canyons and Seamounts Marine National Monument, southeast of Cape Cod. Among that vast diversity, the team spotted Chilean devil rays (Mobula tarapacana). This ethereal fish is “one of the ocean’s best-kept secrets,” according to the aquarium.

“We rarely see Chilean devil rays on our aerial surveys,” Katherine McKenna, a researcher in the New England Aquarium’s Anderson Cabot Center for Ocean Life, tells Popular Science. McKenna was one of the observers on the team that saw the Chilean devil rays from above. 

“The Monument’s deep sea canyons, complex oceanographic conditions, and productive waters support a remarkable diversity of marine life, especially in the summer months when warm water protruding from the Gulf Stream draws in seasonal visitors like Chilean devil rays,” she says.”

Chilean devil rays, also called sicklefin devil rays, are olive-green- or brown-colored and are found in the planet’s tropics and warm temperature seas. These large fish have an 11- to 12.5-foot-wide wingspan and weigh 715 to 1,100 pounds. They’re named after the country where they were first scientifically documented, and McKenna says that the “devil” was inspired by the horn-shaped cephalic fins around their mouths. They are classified as Critically Endangered on the IUCN Red List, and mainly threatened by by-catch and overfishing.

What’s more, the species is relatively difficult to study. They can travel very far, and they are frequently solitary and usually found offshore. When rays like these are found in a group, however, it’s called a “fever.” One thing we  do know is that Chilean devil rays are the deepest diving ray species. They can dive almost 6,000 feet deep. 

“This is possible due to a specialized network of blood vessels surrounding their brain that allows them to keep their brain warm even at very cold water temperatures at deep depths,” says McKenna.

While fall officially began only a few weeks ago, many of us have come to expect pumpkins and Halloween decorations in stores as early as August. And this year, an adorable baby turtle joined in on the early autumnal festivities.

In August, Florida native Michael Landress spotted a loggerhead turtle (Caretta caretta) hatchling making its way toward the water. “This little one, surprisingly, had an earthy tone of autumn. ‘Pumpkin Spice’ sprang to mind as the little orange hatchling raced to its ocean home,” Landress wrote in a statement sent to Popular Science, despite the fact that he doesn’t like pumpkin spice lattes or pumpkin pie.

Loggerhead turtle hatchlings usually have dark to light brown top shells (called a carapace) and dark flippers that can be pale along part of their edges. Their bottom shells (or plastron) is typically a tan or faded yellow, according to Daniel Evans, a biologist at the Sea Turtle Conservancy. Very different shell colors, like “pumpkin spice” or in albino turtles, are rare, Evans adds. 

“For hatchling loggerhead sea turtles, coloration is important for camouflage and hiding from predators while floating in mats of seaweed, such as sargassum,” Evans tells Popular Science. “The common coloration, even with slight variation, provides very good camouflage, while coloration that is different won’t provide that same level of protection. This is most likely why we don’t see such drastic differences in coloration in adult loggerheads.”

Adult loggerhead turtles usually have a more reddish-brown carapace and pale yellowish plastron, as well as brown to yellowish flippers.

Loggerhead turtles are named in honor of their large heads. They live in subtropical and temperate oceans, and Florida is home to one of the largest loggerhead nesting aggregations on the planet. Nonetheless, they are classified as Endangered by the IUCN and federally-designated as Threatened by the United States. A significant threat to the species is bycatch in commercial fisheries.

Squid skin behaves a bit like a large, 10-armed human ear. While scientists at Case Western Reserve University were probing these enigmatic cephalopods, they discovered that squid have significantly more hair cells than was previously known. 

Hair cells are cells with bundles of hair-like protrusions, and researchers already knew that squid had  them on their heads and arms. Now, it looks like the invertebrates have hundreds more of them all over their bodies, with potential insight for understanding human hearing. 

“Squid are cephalopods with a diverse population of hair cells on the surface of their bodies, which may yield insights not only into how these fascinating animals detect water movement to survive, but also into how hearing and deafness occur in humans,” Brian McDermott, a biologist and co-author of a quid study recently published in the journal Current Biology, said in a statement. That’s because these squid hairs are similar to those inside the human ear, which enables us to hear things. 

McDermott (who investigates hair cells) and his colleagues used an imaging technique called light sheet microscopy to probe the cells. During this process, a thin sheet of light lights up one plane of a specimen at a time and researchers can produce detailed 3D images while minimizing tissue damage. Their work also included the first full-body mapping of lateral lines (features made up of hair cell clusters) on squid.

Understanding these hairs have implications for our own ears. Human hearing involves sound vibrations moving to a snail-shaped organ in the inner ear called a cochlea. The cochlea is filled with thousands of hair cells, each of which has a collection of small hair-like features called stereocilia, or cilia. The length of cilia depends on where they are found. If they are in areas where low pitches are detected, the cilia are longer. If they are in high-pitch areas, the cilia are shorter. This positioning helps orient each cell to a specific sound frequency. 

When the sound vibrations reach the cochlea, the cilia move. The hair cells then transmit the signals to the brain via the nervous system, where the messages are turned into meaningful sounds. Marine animals such as squid and octopuses feature similar cilia bundles on their bodies. Their survival appears to depend on detecting various frequencies of water movement, akin to how human ears pick up on sound pitches. 

In other words, squid skin appears to behave like a human ear. This new research even suggests that squids regulate the length of the hair bundles to tune the hair cells to various frequencies, similarly to human ears. The hair bundles in fish lateral lines, on the other hand, are all the same length. So by studying squids, researchers could learn more about human hearing. 

“Often, when a child is born deaf or a hearing person loses their hearing, it is the hair bundle that has been damaged,” McDermott concluded. “So, studying the squid’s hair bundle holds promise for understanding how hearing loss occurs.”
