Periphylla Periphylla – Cold Water Diving in Norway

1

Clip and legend by Jan Roar Gjersvold. The crown jellyfish (Periphylla periphylla) lives all over the world in deep waters. Sometimes, in some Norwegian fjords,  like Lurefjord in Bergen, and Skarnsundet in Trondheim Fjord, the jellyfish can be seen in shallow water.  During the last few years, the crown jellyfishes have been multiplied in the Norwegian fjords, while the diversity of fish has been reduced. The cause is not clear yet but it seems that under certain conditions the jellyfish outperform fish.
