Biologists in Antarctica photograph a deep-sea jellyfish

Scientists from Viking Expeditions photographed a giant deep-sea jellyfish off the coast of the Antarctic Peninsula. Research published in the journal polar research.

Jellyfish Stygiomedusa gigantea is one of the largest deep-sea invertebrate predators. Its tentacles can reach 10 m in length, and the bell is about 1 m in diameter.

It is noted that Stygiomedusa gigantea live in all oceans, with the exception of the Arctic Ocean.

The jellyfish is difficult to spot, as it is usually found at a depth of more than 1 km, writes “Gazeta.Ru”.

The authors of the study managed to capture the jellyfish using a Viking submersible. According to scientists, she showed no interest in the camera and simply floated by.

Scientists have suggested that the jellyfish ended up in the shallow waters of Antarctica to receive ultraviolet radiation, which rids them of parasites.

At the end of April 2022, scientists from the Oceanarium Research Institute in the United States discovered a new species of deep-dwelling jellyfish from the genus Atolla in Monterey Bay. It was noted that such jellyfish are common throughout the planet, and the largest individual of the species is 13 cm in diameter.
