It's been speculated that increasing fishing activity have caused jellyfish predator numbers to dwindle, thus allowing jellyfish numbers to increase. Large masses of jellyfish have been referred to in the ecological and oceanic communities as "jellyfish joyrides".

All jellyfish have the ability to sting their prey, and in massive numbers they become far more hazardous to life. Humans have been victims of jellyfish attacks, sometimes resulting in death due to excessive levels of venom from jellyfish stingers.
