The gelatinous transparent body of a strange jelly-like sea creature — some of which are still hungry for recent meals, illuminated by the shimmer of internal light — footage of hypnosis captured under the Antarctic ice. It rolls and drifts.
Edited into “Trippy Video Works” by filmmaker and scientist Emiliano Shimori Explained the movie in a statementThis footage shows a close-up view of McMurdo Sound’s deep waters of the Antarctic Ocean, the Ross Sea jellies, comb animals, and other soft-bodied sheer marine life.
According to a new study, the very detailed information in the video allowed researchers to find 12 gelatinous animals, of which 2 jellyfish and 3 comb animals are still scientific. Not known.

Cimoli, a co-author of the study and a graduate researcher at the University of Tasmania in Hobart, Australia, shot the footage when he visited. Antarctica To do research in 2018 and 2019. But he wasn’t there to study jellies and comb animals. Rather, he was testing detectors to monitor algae that live under sea ice. Cimoli wrote In the YouTube video description.
“Watermelons play an important role in polar marine food networks and ecosystems,” said Cimoli. “The research theme of the expedition was to investigate its abundance and physiology under changing light conditions.” Climate change, He explained on YouTube.
There was a big hole in the sea ice in the researcher’s outdoor tent. Cimoli, an amateur wildlife videographer and photographer, saw this as an opportunity to send a camera under the ice and look for elusive marine life, which is often difficult to observe in natural habitats.
This opens a window to the rarely glimpsed marine ecosystem, “like a magical portal to another world,” Shimori said in a statement.
In some footage, surface ice is visible overhead. Other clips show the seabed with plenty of pink starfish. But the most dramatic scene is when the jelly floats in the black water and undulates. With amazing shots Diplulmaris antarctica The jellyfish’s body gently pulsates and undulates. Several small orange spheres-small parasitic crustaceans called hyperiidea amphipods-are gathered around the bell. And what is swallowed in the jellyfish is a recent diet: Beloe Genus.
Cimoli edited the video during the blockade of COVID-19 and he posted it YouTube When Vimeo March 2020. Gerlien Verhaegen, a postdoctoral fellow at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Kanagawa Prefecture, Japan, and the lead author of the study, recognized this video as a gold mine for biologists studying jelly. The delicate structure of the squeeze body of jellyfish and comb animals is very difficult to preserve when the animal is taken out of the water, so the author of the study compared it with the illustrations and explanations of the naturalists in the video. Specified the species. At the beginning of the 20th century, Verhaegen said in a statement.
“Our study constitutes the first optical-based study of gelatinous zooplankton in the Ross Sea,” the study authors reported. This is also the first study to describe species of jellies and comb animals and record some of their behavior using observations of jellyfish living in Antarctic habitats.
Scientists have reported sightings of 12 species of these gelatinous animals, but not all of them are consistent with the description in the scientific literature, and five individuals may be unexplained species. There is sex. According to research, images from footage are also used to train computer algorithms to identify jellyfish species. This is only possible if the training database contains high quality photos and videos that the computer can learn.
And after looking into another world’s marine environment under sea ice, people may want to know more about these mysterious remote habitats, Cimoli wrote on YouTube. ..
“When curiosity is aroused, it engages people deeply and encourages them to become more knowledgeable about something,” Cimoli said.
Survey results were released on August 16th Biodiversity Data Journal..
