How jellyfish can help us

Jellyfish blooms can cause havoc, scaring away tourists, clogging up fishing nets, and even getting stuck in power station cooling pipes.

They think jellyfish mucus could filter microplastics from our water systems, and their collagen could help us develop new medicines. And some want to see jellyfish on our plates.
