Researchers are tracking the ocean near Antarctica discovered a new species Which looks disturbing in the pictures, but they named it after a fruit.

Antarctic Strawberry Feather Star is a sea creature 20 of the so-called “weapons”, He pointed out, some bumpy, some feathery, and together they can be up to 12 cm long. insider Greg Rouse, Professor of Marine Biology at the University of California, San Diego.

Rouse co-authored the paper on the new species with researchers Emily McLaughlin and Nereid Wilson and published their findings. invertebrate systematics last month report Science alert.

alien creature At first glance it doesn’t look like a strawberry. But if you move closer to its body, a small bulge at the top of each of those arms resembles the shape and size of a fruit.

The circular protuberances on the body of the star are where the cirri (small, tentacle-like stars protruding from the base) should be, Rouse said, but they have been removed to show the attachment point.

“We’ve removed a bunch of cirri so you can see the parts they’re attached to, and the strawberry looks something like this,” he said.

They are said to have small claws at the end of the cirri that are used cling to the bottom of the ocean floor, indica Science alert.

The so-called arms are the longest and wingest parts of the Antarctic strawberry feather star shown in the image. They are usually dilated, Rouse said, and help with the creature’s mobility.

The place where it was found

The formal name of the new species is Promachocrinus fragarius. It belongs to the class Crinoidea, which includes sea stars, sea urchins, sand dollars and sea cucumbers, and is a type of feather star, hence the less formal name “Antarctic feather star”. According to the paper, fragarius derives from the Latin word “fragum”, meaning strawberry.

The professor said in an interview that there was originally only one species under the Antarctic feather star group: Promachocrinus kerguelensis, he says. Science alert.

But by casting a net across the Southern Ocean in search of more specimens of these creatures, a team of scientists from Australia and the United States identified four new species that may belong to the Antarctic feather star group.

The Antarctic strawberry feather star is particularly distinguished because of its number of “arms”. “Most winged stars have 10 arms” Rose said.

Rouse said the typical position of a winged star is that its “arms” are extended out and up, while Siri points down, he reports. Science alert.

With this discovery, researchers can add eight species under the Antarctic feather star category, adding four new discoveries and “reviving” previously discovered animals that were initially thought to be their own species, Rouse said.

“So we went from one species with 20 arms to eight species, six species with 20 arms and two species with 10 arms called promachocrinus,” Rouse said.

In deep

According to the paper, the Antarctic Strawberry Feather star was found somewhere in between 200 and 3,500 m below the surface.

The researchers acknowledge the “extraterrestrial presence of the swimming activities of feather stars” in their paper.

The Antarctic strawberry feather star was found somewhere between 200 and 3,500 meters below the surface.

But finding new species is generally not a rare occurrence, Rouse said, adding that his lab at the university’s Scripps Institution of Oceanography names 10 to 15 species a year, he says. Science alert.

“We found too many species. The problem is the amount of work that goes into naming them,” he said.
