Orcas that hunt sperm whales may be new population, study suggests – Global News

Published

Researchers from the University of British Columbia said they’ve identified a potentially new population of open-ocean orcas, which hunt the biggest predators on the planet.

In a study published Friday, researchers said a group of 49 orcas has been observed hunting sperm whales off the coast of California and Oregon.

Lead author Josh McInnes said the orcas were seen hunting a herd of nine adult sperm whales, “eventually making off with one.”

It’s the first time killer whales have been reported attacking sperm whales on the West Coast, he said.

“Other encounters include an attack on a Pygmy sperm whale, predation on a northern elephant seal and Risso’s dolphin, and what appeared to be a post-meal lull after scavenging a leatherback turtle,” said McInnes, who is a masters student in the UBC Institute for the Oceans and Fisheries.

Researchers said the orcas that were observed in nine encounters from 1997 to 2021 could either belong to a subpopulation of transient killer whales or a unique oceanic population.

The study said the encounter that was witnessed with the sperm whales occurred in 1997 about 130 kilometres off the California coast. Many of the sperm whales in the pod were left with “extensive injuries,” while one was killed, the study said.

“Approximately 12 killer whales were initially involved in the hunt, but this number increased to an estimated 35 killer whales spread out over 3 km. Small concentrated groups of four to five killer whales randomly targeted and attacked individual sperm whales in the rosette,” the study said, describing how the whales gathered in a circle with their heads together and their tails pointing outward.

“Fresh blood and an oil slick of animal fat could be seen at the surface following each attack,” the study continued.

It said one of the whales was dragged away from the rosette with several orcas seen feeding on it.

In another encounter that took place in 2001 about 350 kilometres off the California coast, seven killer whales from the same group were observed scavenging from a leatherback turtle.

McInnes said scientists collected a lot of photographs and data through these encounters, but they couldn’t match or recognize any of the orcas to other known killer whales in the northeastern Pacific.

He notes there are three different types of killer whales that live along the coast of California and Oregon: residents, transients, and offshores.

The study said the individuals they encountered shared physical similarities with both transient and offshore ecotypes, but were not “a perfect fit” with either.

The report said researchers were able to identify the orcas as possibly a new group partially because of bite scars on their bodies from the cookiecutter shark, a species of parasitic sharks that lives in the deep ocean.

“The presence of cookiecutter shark wounds provides indirect evidence that these unknown killer whales had spent time in warmer oceanic waters,” said the study.

McInnes said almost all of the orcas had the scars, while they haven’t seen them on other killer whales.

“But the big question is, where do these killer whales kind of fit in? We don’t know … but what we do know is that they represent a population that seems to spend more time in the open ocean,” McInnes said in an interview.

Co-author Andrew Trites from the UBC Institute for the Oceans and Fisheries said it’s “pretty unique” to find a new population of killer whales given the time needed to gather photos and recognize the animals as different than known populations.

Researchers said they also observed physical differences in the killer whales such as patches on their fins and saddle.

They said they hope to document more sightings and data from the new population in order to investigate exactly how different these orcas are from other documented populations.

McInnes said the discovery is the first part of a fun puzzle that they are working on.

“We’re just kind of at the tip of the iceberg of what these whales are doing. I mean, are they all one population? Are they multiple? We don’t know. So, I feel like this is kind of the big start of the next steps in our research, and to maybe get more sightings and more information,” said McInnes.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
