All of the baby Otter names submitted through October 20 will be reviewed by the zoo staff. The top four names will be selected and announced on the zoo’s Facebook page for a final vote from October 20 through November 3. The zoo plans to announce the winner on November 10.

Asian Small-clawed Otters live in wetlands and mangrove swamps in Southeast Asia, where they feed on Crustaceans and Mollusks. Every aspect of the Otter’s body is designed for efficient swimming, including the long, torpedo-shaped body, muscular tail, flattened head, and webbed feet. These Otters are the smallest of the world’s 13 Otter species.

Due to habitat degradation, illegal hunting, and pollution of waterways, Asian Small-clawed Otters are listed as Vulnerable by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.  The Kansas City Zoo, along with other accredited North American zoos, participates in the Association of Zoos & Aquariums’ Species Survival Plan to breed rare species and maintain a high level of genetic diversity in populations under human care.

 


Vancouver Aquarium’s Sea Otter Pup Makes a Friend

1_Hardy-Eating-1200x616

The male Sea Otter pup being cared for at the Vancouver Aquarium Marine Mammal Rescue Centre is now four months old. The fuzzy pup, named Hardy, was rescued after concerned members of the public found him swimming alone in open water off northern Vancouver Island back in June.

Since his rescue, staff and volunteers have spent shifts feeding, bathing and grooming the pup. Hardy recently began honing his swimming and diving techniques, and he can’t seem to get enough of practicing his new skills!

Since his arrival, the aquarium has anticipated an appropriate time to introduce the orphan to the rest of the Otters housed at the facility. Hardy was recently introduced to Vancouver Aquarium’s 13-year-old rescued female Sea Otter, Tanu, and she just may prove to be a valuable foster mom for the young pup.

Kristi Heffron, Senior Marine Mammal Trainer, shared, “It took Hardy a moment or two to realize that Tanu had joined him in the Finning Habitat. Then, Tanu went to Hardy and put him on her chest, just like a mother would do to her pup. After a little while, we saw them both swimming, grooming, and eating independently. They’re quite comfortable together.”

ZooBorns introduced the Otter pup to readers back in June when he was first rescued. At that time, Lindsaye Akhurst, Manager of the Marine Mammal Rescue Centre, which is presented by Port Metro Vancouver, made a statement concerning the rescue: “Sea Otters have high energetic needs; after birth they spend about six months with mom, nursing, being groomed by her and learning to forage and be a Sea Otter, so this little guy is still a fully dependent pup. He would not survive on his own, and we’re providing him with the care he needs right now.”

According to the report provided to the Rescue Centre, boaters collected the Sea Otter pup after it approached and then followed their boat while vocalizing. There were no adult Sea Otters in sight. Once in Port Hardy, officers from Fisheries and Oceans Canada (DFO) arranged for the transfer to the Vancouver Aquarium Marine Mammal Rescue Centre. Although well intentioned, both DFO officials and Rescue Centre personnel say the distressed animal should have been reported first rather than taken from the ocean. “Once they’re removed from the wild it’s impossible to determine if the mother is alive and if they could have been reunited, or if bringing him in was the appropriate action,” said Akhurst.

Paul Cottrell, Marine Mammals Coordinator, Pacific Region, DFO, reminds the public that touching or capturing wild marine mammals is illegal. Decisions about the pup’s future will be made by DFO.

Tiny Rescued Sea Otter Pup Growing Stronger

20246323_10154575725475800_4288077242352914843_n
On June 25, the Vancouver Aquarium Marine Mammal Rescue Centre admitted a tiny male Sea Otter pup as a patient. The fuzzy-faced otter pup, now estimated to be about two months old, was found swimming alone in open water off northern Vancouver Island and brought to the Rescue Centre by a concerned citizen.

You first met the pup on ZooBorns when he was just a few weeks old. Since his arrival at the Rescue Centre, the tiny otter has received 24-hour care from staff and volunteers who feed, bathe and groom him, just as his mother would in the wild. Baby Sea Otters cannot survive on their own, and depend on their mothers for the first six months of life.

Care and rehabilitation of rescued marine mammals is very labor-intensive, and it takes a whole team of dedicated staff and volunteers to care for this tiny pup.

The little Otter continues to gain weight steadily and has been growing stronger and more active. He now weighs nearly nine pounds and is growing quickly. He is still nursing from the bottle, and drinks 25 percent of his body weight per day in a special Otter pup formula made by the animal care team.  This week, the baby Otter was offered his first solid food – five grams of clams, which he gobbled up enthusiastically.  He eats every three hours, 24 hours a day.

The care team says the pup is curious and enjoys exploring. He pup is now grooming himself a little bit, but still needs help from the care team to remain clean and fluffy.  They also report that the pup is learning to dive and can dive to the bottom of his swim tub to retrieve toys.

Sea Otters are and Endangered species. They were hunted for their fur until the early 20th century, when their population fell to just a few thousand individuals in a tiny portion of their former range. Bans on hunting and other conservation measures have helped, but Sea Otters are still threatened by fishing net entanglement and oil spills.

 


Vancouver Aquarium Cares for Rescued Sea Otter Pup

A tiny male Sea Otter pup, estimated to be just two to four weeks old, is now in 24-hour care at the Vancouver Aquarium Marine Mammal Rescue Centre, after concerned members of the public found it swimming alone in open water off northern Vancouver Island on Sunday.

Although the pup appears healthy, he requires care night and day from the Rescue Centre team, just as he would from his mother. Staff and volunteers are spending shifts feeding, bathing and grooming the newborn pup, which has not yet been named.

“Sea Otters have high energetic needs; after birth they spend about six months with mom, nursing, being groomed by her and learning to forage and be a Sea Otter, so this little guy is still a fully dependent pup. He would not survive on his own, and we’re providing him with the care he needs right now,” said Lindsaye Akhurst, Manager of the Marine Mammal Rescue Centre, which is presented by Port Metro Vancouver.

Once extinct from Canada, the Sea Otter (Enhydra lutris) has successfully been reintroduced to British Columbia, and mainly lives off Vancouver Island. Subsequent population growth and range expansion enabled the Government of Canada to change the listing of the species from “Threatened” to “Special Concern” in 2009, as recommended by COSEWIC.

Major causes of death among Sea Otters are lack of food, predators and environmental contamination. A recent study, conducted by researchers from UC Santa Cruz, U.S. Geological Survey and the Monterey Bay Aquarium, and published in the Journal of Experimental Biology, found the energetic cost of rearing Sea Otter pups could also be leading to higher mortality rates in adult females, and more incidents of pup abandonment.

The Vancouver Aquarium Marine Mammal Rescue Centre, a hospital for sick, injured or orphaned marine mammals, is the only one of its kind in Canada. Under authorization from DFO, the team rescues, rehabilitates and releases more than 100 animals each year; in 2016, they rescued more than 170 animals. For every patient, the goal is to treat, rehabilitate and return it to the wild as soon as possible. The veterinary team provides medical treatment to Harbor Seals, Sea Otters, Sea Lions, Sea Turtles, Elephant Seals, Whales, Dolphins, and Porpoises.

This year’s rescue season is proving to be a busy one already. As well as the Sea Otter pup, the Rescue Centre has provided assistance and care to a California Sea Lion, a Steller Sea Lion pup, and 29 Harbor seals.

The Vancouver Aquarium would like to remind the public, if you see a stranded marine mammal, do not approach it and keep domestic pets away. Call the Vancouver Aquarium’s Marine Mammal Rescue Centre at 604.258.SEAL (7325) for immediate assistance.

Saved at Birth, Baby Otter Comes Out of the Nest

Otter Pup 6_Photo by Paul Fahy
An Otter pup whose life was saved by an emergency Caesarean section is out of the nest at Taronga Zoo.

When a female Oriental Small-clawed Otter named Pia went into labor on February 28, keepers noticed that she was having difficulty delivering her babies.  They called on the veterinary staff, who performed an emergency Caesarean section on Pia.  Unfortunately, all three of Pia’s cubs were unresponsive when they were delivered.

The staff tried to resuscitate the cubs, and amazingly, one survived.  That pup, a male named Intan, which means ‘diamond’ in Indonesian, has spent the last 10 weeks in the nest box with Pia and her mate, Ketut. Intan has just begun exploring outdoors and tasting solid food alongside mom and dad.

“They’ve been perfect parents. They’re both extremely attentive and occasionally even battle over who gets to look after the pup,” said Keeper Ben Haynes.  “Ketut is a first-time dad, but he grew up with younger siblings so he has experience collecting fish and caring for younger otters.”

The pup is the first successful Otter birth at Taronga in more than 15 years.

“He’s very curious, but still very much reliant on mum and dad for everything. They’ve started encouraging him into the water, swimming alongside him and teaching him to dive underwater,” said Ben.

The smallest of the world’s 13 Otter species, weighing less than 12 pounds as adults, Oriental Small-clawed Otters are found in the streams, rivers, marshes, and wetlands of southern India, southern China, Southeast Asia, Indonesia, and the Philippines.

Classified as a Vulnerable species by the International Union for Conservation of Nature, populations continue to be threatened by habitat loss, water pollution and poaching for the fur trade.

Otter Trio Debuts in Time for Mother’s Day

1_5 days old

A lively trio of North American River Otter pups recently made their debut at Oakland Zoo. A male and two females were born February 9, and they were introduced to the public prior to Mother’s Day weekend. According to keepers, their mom, Rose, has been doing a great job taking care of her new litter.

Zookeepers have also given names to the active pups. The boy has been named Si’ahl (“see-all”), and his sisters have been named Imnaha (“em-na-ha”) and Talulah (“ta-lou-la”).

The arrival of the pups brings the total number of North American River Otters, at Oakland Zoo, to six: their mom, dad Wyatt, and grandma, Ginger (Ginger is mother to Rose).

The pups are still nursing, but have begun eating solid foods consisting of fish and some meat.

Dad, Wyatt, is Oakland Zoo’s only adult male and was relocated to Oakland three years ago from the Abilene Zoo, in Texas, where the Association of Zoos and Aquariums (AZA) gave him a breeding recommendation.

“We are pleased to have our sixth healthy litter of Otter pups since 2011. This is Rose’s second litter, and we are happy that she is once again being a great mother to her pups. You can see Rose and her three pups daily at the Oakland Zoo, in the Children’s Zoo,” said Adam Fink, Zoological Manager, Oakland Zoo.

Zookeepers have been tracking the baby Otters’ growth and health with bi-weekly checkups, referred to as "pupdates" to Zoo staff. Rose has only very recently been venturing into the exhibit with her pups. Swimming is not instinctual; therefore, pups do not go on exhibit until they are strong enough swimmers and a certain size.

Zoo guests are now able to watch the new pups in their exhibit daily. The River Otter exhibit is located in the Wayne and Gladys Valley Children's Zoo.

You ‘Otter’ See Brookfield Zoo’s New Pups

1_North American river otter pups (18 days old)-2

The Chicago Zoological Society is thrilled to announce the birth of twin North American River Otter pups at Brookfield Zoo. The male and female pups, born on February 23, are the first successful births of this species in the Zoo’s history.

The adorable siblings are currently behind the scenes, bonding with their mom, learning how to swim. They are scheduled to make their public debut later this month.

The pups’ mother, Charlotte, arrived at Brookfield Zoo in June 2012 from Omaha’s Henry Doorly Zoo. The father, Benny, joined the Zoo family from Dickerson Park Zoo in Springfield, Missouri, in August 2004.

Otter mating typically occurs between December and April, with most births occurring between February and April of the following year. Pups are born with their eyes closed, fully furred, and weighing about 4 ounces.

The Chicago Zoological Society (CZS) is a participant in the Association of Zoos and Aquariums’ (AZA) North American River Otter Species Survival Plan (SSP), which is a cooperative population management and conservation program for the species. The program manages the breeding of Otters in zoos to maintain a healthy and self-sustaining population that is both genetically diverse and demographically stable.

The North American River Otter (Lontra canadensis) is a semiaquatic mammal endemic to the North American continent found in and along its waterways and coasts. It is a member of the subfamily Lutrinae in the weasel family (Mustelidae).

An adult River Otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). The River Otter is protected and insulated by a thick, water-repellent coat of fur.

North American River Otters, like most predators, prey upon the most readily accessible species. Fish is a favored food, but they also consume various amphibians (such as salamanders and frogs), freshwater clams, mussels, snails, small turtles and crayfish.

The International Union for Conservation of Nature (IUCN) lists these Otters as “Least Concern”, meaning that the populations are very stable. However, habitat degradation and pollution are major threats to their conservation.


Litter of Seven Otters Born at Wingham Wildlife Park

1_crop_20170413_083739

On March 16, a female Smooth-coated Otter, living at Wingham Wildlife Park in Kent, UK, gave birth to seven beautiful babies.

The new mum, Pong, originally arrived at Wingham Wildlife Park in August 2011, from the Rare Species Conservation Centre, a small zoological park on the outskirts of Sandwich in Kent, which the team at Wingham Wildlife Park took over and re-branded as Sandwich Wildlife Park in January 2017.

Pong is now almost seven-years-old, and this is her second litter of pups, with her first litter having been moved to other zoos in the UK, France and even the Czech Republic. Just like the last litter of pups, the father is nine-year-old Bob, whose birthday is just one day after the babies on March 17.

Bob was named by the park's Facebook followers, along with his other girlfriend, “Sheila”. Bob arrived at Wingham Wildlife Park in January 2013 from the Saigon Zoo & Botanical Gardens in Southern Vietnam.

At present, there are 17 males and 16 females in Europe, and with many of these coming from a single pair imported in to the UK from Cambodia several years ago (Pong’s parents), more individuals, which are at least half unrelated to the rest of the European population, is once again good to see.

The park looks forward to Bob hopefully breeding with Sheila in the future, who came from Zoo Negara in Malaysia which would give some completely unrelated offspring in the European genepool. With 10 of these individuals living at Wingham Wildlife Park at present, this gives the park the largest collection of Smooth-coated Otters in Europe.

Having babies is always very exciting for the staff at Wingham Wildlife Park, and the keepers for those animals are always very proud when the babies are born and are growing well and looking healthy.

On April 13, the babies were removed for just a short time from Pong to allow the head of carnivores, head keeper, and curator of the park to weigh the pups, give them a visual health check, microchip them and find out what sex they are. In the end, it turned out that the babies consisted of two females and five males: making the sex ratio in Europe almost equal. At four-weeks-old, especially with one mum rearing seven hungry mouths, their weights came up between 390g and 500g, with most of them weighing just over 390g, with one extra hungry baby in the bunch.

Tony Binskin, the owner of Wingham Wildlife Park said of the arrival, “It has been a couple of years since we last had baby Otters, so this was a really nice sight to see! Even though this is quite a few mouths to feed, we know from past experience that Pong is a great mum, and have no worries about her.”

At four-weeks-old, they now all have their eyes open, however they are still far from independent so it will still be a little while before they start to venture outside. For now, they are spending all their time curled up in a tight ball of babies in their nest box, which Pong had been preparing for a few days before giving birth.

When the babies start to venture outside it will be an exciting time for the staff at the park, as Tony finished by saying: “Baby Otters are definitely some of the most interesting animals in the whole park. It is always a very tense moment however when mum first teaches the babies about the water, as she picks them up, one by one, and dunks them in the pond. Just like the babies, we’re always at the side of the enclosure for this experience, holding our breaths until the swimming lesson is over!”

The Smooth-coated Otter (Lutrogale perspicillata) is the only extant representative of the genus Lutrogale. This Otter species is found in most of the Indian Subcontinent and eastwards to Southeast Asia, with a disjunct population in Iraq. As its name indicates, the fur of this species is smoother and shorter than that of other Otters.

The Smooth-coated Otter is currently listed as “Vulnerable” on the IUCN Red List of Threatened Species. Their range and population are shrinking due to loss of wetland habitat, contamination of waterways by pesticides, and poaching.

Park staff encourages fans of the new pups to check their Facebook page for updates about when these beautiful animals will start to venture outside and make their public debut: https://www.facebook.com/WinghamWildlifePark


Twin Otter Pups Born at Oregon Zoo

30717Op-100

Tilly, a North American River Otter, is raising two tiny pups, born February 26 at the Oregon Zoo. The new arrivals — one male and one female — weighed around 4 ounces each at birth and have already doubled that thanks to their mother's naturally high-fat milk.

"Young River Otters are extremely dependent on their moms, and Tilly has been very nurturing," said Julie Christie, senior keeper for the zoo's North America area. "She did a great job raising her first two pups, Mo and Ziggy, both born in 2013. And she was a terrific adoptive mom to Little Pudding, the orphan pup who was rescued from a roadside in 2015. We expect she'll do well with her new babies as well."

Tilly and her pups are currently in a private maternity den, and it will likely be another month or two before visitors can see them in their Cascade Stream and Pond habitat. Young River Otters usually open their eyes after three to six weeks, and begin walking at about five weeks. Surprisingly, swimming does not come naturally to River Otters — pups must be taught to swim by their moms.

Keepers have yet to decide on a name for the two new pups, though it is likely they will be named after Oregon rivers or waterways like their older siblings.

"This will be the first time Tilly has raised more than one pup at a time," said curator Amy Cutting, who oversees the zoo's North America and marine life areas. "It's exciting that they'll be growing up together and have the opportunity to play and wrestle with each other. Tilly's always been an extremely attentive mother, so it will be interesting to see what happens when her pups go in two different directions."

Woodland Park Zoo's Otter Pups Pass First Vet Exam

1_ASCO pup exam-3_Jeremy Dwyer-Lindgren_2.3.17

The four Asian Small-clawed Otters born at Woodland Park Zoo received their first veterinary examination last week. The zoo’s animal health team assessed their overall health, measured and weighed the pups, and administered vaccinations.

The wellness exam is a part of Woodland Park Zoo’s exemplary animal care program. The exam revealed the pups to be three males and one female. They currently weigh between 0.6 to 0.7 kilograms (1.3 to 1.5 pounds).

Dr. Darin Collins, Woodland Park Zoo’s director of animal health, gave the pups a clean bill of health. “We’re pleased to report all four pups are robust and healthy. They have fully round bellies and are within normal growth range at this age,” said Collins. “All pups have healthy appetites, are gaining increased mobility and are socializing with their family members, all good signs they’re thriving.”

ZooBorns introduced readers to the quad of cuteness in a recent article (found here), and we are more than happy to provide updates on their progress. The pups were born December 9 at Woodland Park Zoo to 7-year-old mother Teratai and 11-year-old father Guntur. The birth represents the third litter for the parents.

The new pups currently live off view in a maternity den with their parents and three older sisters. Raising Otter pups is a family affair—the whole family plays a role in raising the pups. Mom nurses the newborns, and dad and older siblings provide supportive care. Occasionally, the adults go outdoors for short periods in the public exhibit but primarily spend their time indoors to focus on caring for the pups.
