New species of sea worm found in the southern ocean

The brand new species of worm is one in every of six species of Flabelligena, that are primarily from the North Atlantic Ocean.

The early researcher will get the ocean worm. On this case, a crew of scientists from Japan’s National Institute of Polar Research, National Museum of Nature and Science, and Kochi University discovered a brand new species of sea worm — they named Flabelligena Gillet 2001.

The invention was made when the scientists have been amassing specimens from the seafloor at depths of two,036 to 2,479 meters, within the South Orkney Islands within the Southern Ocean.

When the scientists seemed on the specimens beneath a microscope and photographed them with a high-resolution digital digital camera, they observed the brand new sea worm.

In response to the crew’s analysis, which was revealed in Biodiversity Data Journal in June, the Flabelligena Gillet 2001 sea worm has a “minute” yellow physique, physique papillae (small rounded protuberance), 1-Three pairs of gill-like organs referred to as branchiae, and two frontal palps. Its physique is about 1.eight centimeters lengthy and 1 millimeter broad. Each ends of the ocean worm are rounded.

The brand new species of worm is now one in every of six species of Flabelligena and is taken into account a part of the category of worms referred to as polychaetes, which incorporates over 10,000 species. The brand new sea worms dwell in sandy mud areas, primarily in underwater at 1,000 meters and deeper.

“Polychaetes are one of the various teams in marine benthic animals and well-studied within the Southern Ocean,” analysis crew chief Naoto Jimi mentioned in a statement on Aug. 12.”Many researchers have investigated the Southern Ocean, however our information of small deep-sea invertebrates continues to be fairly restricted.”

This new species is the primary document of Flabelligena discovered within the Southern Ocean. Different already recognized Flabelligena sea worms are discovered primarily from the North Atlantic Ocean — three of that are recognized from the Southwest Atlantic, Mediterranean, and South Indian Oceans.
