Narwhals may be using their tusks to play, new study finds
лаки джет официальный сайт
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.
Narwhal exploratory behavior
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.

Знайшов наукову статтю у них, і вона була так гарно написана, що прочитав на одному диханні! Респект авторам.

Тени Химок и Лобни

Алина проснулась в крошечной квартире на окраине Эскорт Химки.
От резкого света фонаря за шторой заломило виски — снова короткий сон перед ночной сменой.
Она затянулась сигаретой, глядя на потрескавшиеся обои. Деньги за аренду копилки не ждали.
Экортницу Лобня встретила её холодным ветром. Здесь клиенты были проще — водители с трассы, одинокие мужики из спальных районов.
Иногда везло: попадались «благодарные», оставляли сверху пару тысяч. Но чаще — торг, хамство, а то и кулаки.
Однажды зимой её забрали в отделение. Допрос, унижения, взятка «за молчание». После этого Алина научилась договариваться заранее.
К весне накопила на билет в Сочи. Мечтала о море, чистом небе. Но когда пришло время уезжать, обнаружила, что даже чемодан собрать страшно.
Химки и Лобня стали её клеткой.
Алина поняла это, стоя на перроне, глядя на уходящий поезд. В кармане — пачка смятых купюр. Завтра — новый день. И новый клиент.

Одного вечора, коли ми з друзями шукали, який виступ подивитися на Trance Illusion, нам порадили не пропустити Kutty. Ми підійшли до сцени, і те, що ми побачили, повністю змінило наші уявлення про візуальні шоу. Вона створила такий гіпнотичний світ, що навіть ті, хто прийшов випадково, залишилися і стояли, заворожені. Коли вона синхронізувала світло з енергійними транс-ритмами, у глядачів виникало відчуття, ніби вони перебувають у зовсім іншій реальності. Це був виступ, який ми потім ще довго обговорювали. Якщо хочете дізнатися більше, завітайте на її сайт.
