estimated the oceans are home to about 2.2 million species, with only 9% having been recorded in databases at that time.in June, describes a newly discovered Antarctic feather star with 20 tentacles that might indicate the presence of far more types of invertebrates in the ocean than previously believed.
"We did two expeditions to Antarctica assessing connectivity between South America and the Antarctic peninsula and also other cruises and samples were used for assessing circumstances-Antarctic species", Rouse toldThe marine expert revealed that his team examined thousands of invertebrates during the expeditions, but none were nearly as interesting as Antarctic feather stars. "We sampled many different groups", said Rouse.
The samples were collected from different area of the Southern Ocean, and classified after DNA sequencing allowed the scientists to take a closer look at the purple to dark red animals' complex morphology. The Antarctic strawberry feather star was found to fall under the Crinoidea class, which also contains sea urchins, starfish, sand dollars, and sea cucumbers. Rouse said the inspiration for its name came from the Latin word for strawberry -Promachocrinus fragarius
