Orca successfully delivers healthy calf after carrying deceased newborn over 1,000 miles

The orca who captured hearts worldwide in 2018 by refusing to let go of her deceased calf has now welcomed her second baby in the last four years.

The Whale Research Center has confirmed that their team has started monitoring the new baby girl on Monday, giving her the alphanumeric name “J61.” They are closely monitoring and observing the calf’s well-being.

The mother, known as Tahlequah with the designation number J35, is an experienced mother. The center is concerned about the health of both J61 and her mother during this critical period.

The early years are especially risky for newborn calves, with high mortality rates in the first year. The Center for Whale Research expressed their hope that J35 will be able to keep J61 safe through this challenging time.

Tahlequah made headlines globally in 2018 when she carried her deceased calf for 17 days, moving people around the world with her display of grief. Her actions prompted Washington State Governor Jay Inslee to establish the Southern Resident Killer Whale Task Force for conservation efforts.

J61 is Tahlequah’s third surviving calf, following J47 or “Notch” born in 2010 and J57 or “Phoenix” born in 2020. They belong to the J pod of killer whales, residing in the coastal waters between Washington state and Vancouver Island, British Columbia.

The J-Pod is one of three pods of Southern Resident killer whales, totaling about 73 orcas across the pods. Conservation groups are working to protect and restore the declining population of these majestic creatures.

Threats to killer whales include entanglement in fishing nets, food scarcity, human interference, and environmental pollution. The declining population highlights the urgent need for conservation efforts to protect these endangered animals.

Contaminants in the water pose a significant threat to orcas, with industrial chemicals accumulating in the food chain and affecting the health of the whales. Female southern whales and their offspring are particularly vulnerable to these pollutants.

NOAA’s 2022 pod health assessment raises concerns about the impact of contaminants on the Southern Resident killer whale population, emphasizing the need for immediate action to protect these magnificent creatures.

Video captured of Blue whale mother nursing her calf for the first time

The first ever video footage of a blue whale nursing a calf was captured by a snorkeler in East Timor, Southeast Asia, and has been released.

“It’s certainly not a newborn calf.” Karen Edivain “But they’re clearly still drinking milk,” said the researcher, from the Australian National University in Darwin.

Edibane says capturing the footage is an incredible feat that has never been achieved before. The action was captured on camera by a snorkeler on an ecotourism voyage swimming with the pygmy whales off the coast of the capital, Dili, in 2022, and has only now been made public.

Blue Whale (Mushibaga) is the largest known animal to have ever lived on Earth, sometimes reaching lengths of over 30 meters and weighing nearly 200 tons.Southern wolfThe sharks found off the coast of Timor-Leste are slightly smaller, reaching a maximum length of 24 metres.

Blue whale calves do not attach to their mothers when feeding, but rather release oily milk into the water, which the calf swallows.

Edivain said the large calf seen feeding in the video is probably in its second year of living with its mother — blue whales are weaned at three years.

Other significant blue whale behaviours have been sighted and filmed in the area as part of the decade-long study. Citizen Science Projects Project leader Edivine said a database of 2,700 pygmy blue whales had been compiled since 2014 and that Timor-Leste may be a base for one of the world’s largest migrations of pygmy blue whales.

Newborn calves, courtship behaviour, pre-mating behaviour and feeding behaviour have all been observed.

“We haven’t seen a penis yet, but we’ve seen very affectionate adults having a lot of fun playing with each other,” Edivain said.

Caprivec The head of marine life conservation for the Western Australian Water Environment Regulatory Authority said that until recently no one knew how many blue whales were migrating off the coast of Timor-Leste.

Beck says he was incredibly lucky to capture the footage. Blue whales are often found far offshore, in hard-to-reach locations. “It’s incredibly rare to even be in the water with a blue whale, and even rarer to be in the water at the right time and place to film a calf nursing.”

Uncommon footage captures killer whale guiding its calf in hunting and launching a dolphin high into the air

A rare video was captured this week by a whale-watching trip off the coast of San Diego, showing an orca teaching its baby how to hunt by headbutting a dolphin and flipping it over multiple times in the air.

Wildlife filmmaker Domenic Biagini, who shot the footage, described the scene, saying: “The killer whale catches the dolphin, but when the dolphin slows down, he releases it after it is subdued and brings the baby killer whale with him to catch it himself.” “Seeing that level of communication and understanding was like watching a family.”

Biagini owns Gone Whale Watching, one of several companies that spotted a pod of six orcas off the coast of San Diego on Monday. He said the orca hunt took about 30 minutes, which was much longer than the average orca hunt because he was teaching orca pups.

According to marine biologist Alisa Shulman Janiger, killer whales are among the ocean’s apex predators and are known to incorporate their large size and speed into their hunting strategies. She added that it is common for orcas to slow down the prey and show the children how to hunt.

Shulman-Janiger explained that the killer whales in the video are so young that their eye patches are yellow instead of white, a color that eventually fades as they get older.

Where do whales come from?

Shulman Janiger said the whale in Biagini’s footage is an eastern tropical Pacific orca, which typically lives in waters off Mexico and Central America. They are rarely seen in the relatively warm, calm waters of Southern California.

Speaking about the hunting behavior, Biagini said, “We try to explain to our guests that while what whales do to dolphins can sometimes be very gruesome, this is normal and healthy.”

Biagini also mentioned that after Monday’s hunt, the killer whales approached the boat to see what was going on and began to poke their heads out of the water, which is a behavior known as spy hopping.

‘Remember us at your Thanksgiving feast’: Killer whales celebrate the hunt

Biagini said the killer whales often celebrate after a successful hunt and zigzag back and forth through the water. He compared it to the feeling of happiness and smiling after a Thanksgiving meal.

Additionally, Biagini expressed concern about the increasing number of boats getting close to orcas to film social media videos, urging people to film animals in the most ethical way.

Danger of flocking to whale watching

Biagini also raised concerns about the number of boats surrounding the pod of killer whales, stating that too many boats with inexperienced operators could interfere with their hunting behavior or lead to collisions.

In a video he shot, a man driving a boat by himself abandons the wheel to lean out onto the deck to record the video.

Overall, Biagini emphasized the importance of being stewards of animals and approaching them in an ethical way.
