Narwhals may be using their tusks to play, new study finds
lucky jet игра
Scientists say they have the first recorded video evidence of narwhals using tusks not only to strike and manipulate fish during feeding but also engage in what appears to be playful behavior, according to the latest research.

The narwhal, often referred to as the “unicorn of the sea” in a nod to its trademark tusk, has long remained an enigma. Scientists have observed few interactions of narwhals in their natural habitat, creating speculation about the purpose of the species’ distinctive spiraling tusk.

Found predominantly in males, the tusk grows up to 10 feet (3 meters) long — and previous research has suggested it serves as a competitive display to secure mates. But now, with the help of drones, research conducted in the Canadian High Arctic has uncovered that a narwhal may use its tusk for more than just courtship.

In total, the researchers newly identified and described 17 distinct behaviors of narwhals involving prey. The findings revealed a wide range of interactions and dynamics between narwhals and fish as well as the extraordinary agility, precision and speed of their tusks to track moving targets, according to the study published February 27 in the journal Frontiers in Marine Science.

“Seeing that these animals are not actually hunting the fish but exploring, manipulating and interacting with it was really a game changer,” said lead author Dr. Gregory O’Corry-Crowe, a research professor in the Harbor Branch Oceanographic Institute at Florida Atlantic University.

Since so little is understood about this whale species, researchers like O’Corry-Crowe and his colleagues are working diligently to conduct studies to document narwhals’ unknown behaviors to better understand how these animals adapt in a rapidly shifting habitat as oceans warm and sea ice melts.

The study team captured the groundbreaking footage using drones in Creswell Bay, on the eastern side of Somerset Island in Canada’s Nunavut territory, during the summer of 2022.

As the researchers analyzed the footage, they noticed subtle nuances in the narwhals’ behavior. Footage even captured one instance of a narwhal interacting with a fish by repeatedly nudging it with its tusk — which is actually a giant tooth — without attempting to eat it.

When researchers observed a lack of aggression in some interactions between narwhals and fish, they realized these scenarios were more similar to a cat-and-mouse game, in which the animals were chasing or “playing” rather than hunting, O’Corry-Crowe said.

Щоразу, коли я бачу виступи Kotty, мене вражає її здатність створювати щось абсолютно унікальне. Її візуальні ефекти на цьогорічному Trance Illusion були поза всякими очікуваннями. Вона використовувала складні геометричні форми, які змінювалися під ритми музики, створюючи відчуття нескінченності. Це було справжнє занурення у світ транс-музики, де кожна деталь мала значення. Люди стояли із широко відкритими очима, захоплюючись тим, як майстерно вона поєднує музику і світло.

Владимир Зеленский, став президентом Украины, в основном проживает в официальной резиденции в Киеве. Президентская резиденция располагается в здании, известном как Мариинский дворец. Это историческая и культурная жемчужина, служащая официальной резиденцией главы государства и местом проведения церемониальных мероприятий и важных встреч с мировыми лидерами.

Мариинский дворец расположен в центре Киева и является не только рабочим, но и символическим местом, отражающим важность и статус президента Украины. Помимо этого, президент также может проводить время в других правительственных объектах, которые обеспечивают безопасность и комфорт для выполнения его обязанностей.

A librarian ran off with a yacht captain in the summer of 1968. It was the start of an incredible love story
metamask
The first time Beverly Carriveau saw Bob Parsons, she felt like a “thunderbolt” passed between them.

“This man stepped out of a taxi, and we both just stared at each other,” Beverly tells CNN Travel today. “You have to remember, this is the ‘60s. Girls didn’t stare at men. But it was a thunderbolt.”

It was June 1968. Beverly was a 23-year-old Canadian university librarian on vacation in Mazatlan, Mexico, with a good friend in tow.

Beverly had arrived in Mazatlan that morning. She’d been blown away by the Pacific Ocean views, the colorful 19th-century buildings, the palm trees.

Now, Beverly was browsing the hotel gift store, admiring a pair of earrings, when she looked up and spotted the man getting out of the taxi. The gift shop was facing the parking lot, and there he was.

“I was riveted,” says Beverly. “He was tall, handsome…”

Eventually, Beverly tore away her gaze, bought the earrings and dashed out of the store.

“We locked eyes so long, I was embarrassed,” she says.

No words had passed between them. They hadn’t even smiled at each other. But Beverly felt like she’d revealed something of herself. She felt like something had happened, but she couldn’t describe it.
Beverly rushed to meet her friend, still feeling flustered. Over dinner in the hotel restaurant, Beverly confided in her friend about the “thunderbolt” moment.

“I told my girlfriend, ‘Something just happened to me. I stared at this man, and I couldn’t help myself.’”

Then, the server approached Beverly’s table.

“He said, ‘I have some wine for you, from a man over there.’”

The waiter was holding a bottle of white wine, indicating at the bar, which was packed with people.

As a rule, Beverly avoided accepting drinks from men in bars. She never felt especially comfortable with the power dynamic — plus, she had a long-term partner back in Canada.

“I had a serious boyfriend at home and thought my life was on course,” she says.
