According to numerous scientists, these blooms suggest that all is not well within the ocean, perhaps something to do with climate change, pollution, overfishing, or a combination of all three. They have a nerve base that coordinates their movements. Even though the Box Jellyfish is a very aggressive type of species there are still some predators it has to contend with. Gershwin is concerned about the state of the oceans and the fate of the creatures within it, but she is not inherently averse to jellyfish. “When there’s an international jellyfish conference, it usually means I’ve gone somewhere,” she says. “They do have huge metabolic demands,” says Gershwin. I have booked a snorkeling trip to the Barrier Reef out of Port Douglas and have heard about something called a box jellyfish in Australian waters that can be lethal. Some jellyfish are harmless, others have a relatively mild sting, and some creatures look like jellyfish but really are not. They don’t just float along in the water and take what comes along.
