What are the threats of the mauve stinger jellyfish?
When large numbers of this oceanic species are washed ashore, the local economy can be affected because tourists avoid the beaches and fishers are stung while trying to retrieve their nets, which can be clogged by the jellyfish.

Where does the mauve stinger live?
Mediterranean sea

Where can I find Pelagia noctiluca in Tanzania?

What happens to Pelagia noctiluca when a diver swims past them?
With Pelagia noctiluca if a diver swims past them, the wash from the fins blows them off course and they are swirled around. Once the effects of the swirl are over, there is a pause and then they usually resume their previous activity. Presumably this pause is caused by the decentralized logic system resetting its self.
