Chrysaora hysoscella

The population of poisonous compass jellyfish, which unlike other marine species can thrive in warm water, has increased in the Marmara Sea as the temperatures are rising with the onset of summer, making the sea a perfect habitat, warns an expert.

In the Dardanelles, located in the western province of Çanakkale, poisonous compass jellyfish whose numbers have been increasing since last year, have negatively affected the fish population, an expert has warned.

Compass jellyfish (chrysaora hysoscella), whose natural habitats are the Mediterranean and the Aegean, are now seen more frequently in the Dardanelles.

A poisonous species of jellyfish, commonly called compass jellyfish, has been infesting the Çanakkale Strait and spearing into the Marmara Sea, an expert has said, warning people to keep away from them.
