Are there jellyfish in the Arctic Ocean?

Yes, there are jellyfish in the Arctic Ocean. One well-known species of jellyfish found in the Arctic is the lion's mane jellyfish (Cyanea capillata). It is one of the largest jellyfish in the world, with a bell that can grow up to 2 meters (6.5 feet) in diameter and tentacles that can trail up to 30 meters (98 feet) long.

Arctic jellyfish have adapted to the extreme conditions of the Arctic Ocean, including cold temperatures, limited sunlight, and low levels of food. Some species of jellyfish, such as the comb jellyfish (Beroe spp.), have antifreeze proteins that prevent them from freezing in sub-zero temperatures. They also have bioluminescent organs that allow them to communicate with each other in the dark waters of the Arctic.

However, the Arctic Ocean is undergoing rapid changes due to climate change, including sea ice loss, ocean acidification, and warming temperatures. These changes are likely to affect the survival and distribution of jellyfish in the Arctic Ocean. Scientists are currently studying the impact of climate change on Arctic jellyfish and other marine life to better understand the future of the Arctic ecosystem.
