In the Chukchi Sea found “Arctic jellyfish”

Scientists from Columbia University filmed a rare compass jellyfish that lives in the Chukchi Sea.

Specialists did not expect to see jellyfish in winter, these shots became a surprise for them. In the study, they found that the compass jellyfish is able to survive in the harsh conditions of the Arctic only if it has reached the “adult” age.

For the research, we used underwater drones, capable of operating under severe conditions. Now scientists are inclined to believe that the winter even positively affects the hydroids – a thick layer of ice protects them from restless waters, and lower temperatures slow down the metabolism, which requires less food.

The population of jellyfish in the Chukchi Sea tends to decrease. Among the reasons scientists call climate change, adversely affecting the marine fauna.
