Jellyfish of the Arctic Ocean: Species and Adaptations

Yes, jellyfish inhabit the Arctic Ocean. Notable species include:

• Lion's mane jellyfish (Cyanea capillata): One of the largest, with a bell up to 2 meters wide and tentacles trailing 30 meters.
• Comb jellies (Beroe spp.): Possess antifreeze proteins to survive sub-zero temperatures and bioluminescence for communication in dark waters.

These adaptations allow them to thrive in extreme cold, limited sunlight, and low food availability. However, rapid climate change—sea ice loss, warming, acidification—threatens their survival and distribution. Scientists are actively studying these impacts on the Arctic marine ecosystem.
