Jellyfish: our complex relationship with the oceans' anti-heroes
The courier hands me an unassuming brown box with “live animals” plastered on the side.

- The cardboard exterior gives way to a white polystyrene clamshell, cloistering a pearly sphere-shaped, water-filled bag.
- The Californian Monterey Bay Aquarium’s Jellyfish: Living Art was the organisation’s most popular and long-running exhibit since opening in 1984.
- A study has shown eating cannonball jellyfish, for example, can reduce the effects of arthritis – albeit so far only in a small group of rats.
A biological wonder
- For example, immortal jellyfish (Turritopsis dohrnii) sidestep the ageing process by reverting to their polyp stage.
- Crystal jellies’ (Aequorea victoria) green fluorescent protein (GFP), found in organs within the animal’s bell, allows scientists to study gene expression.
- Gene expression is the instruction manual DNA follows, for example, to become proteins.
- This gives the crabs security and research suggests jellyfish hosting crabs grow larger than those without, but it’s not clear why.
Sea curiosities
- Research suggests ocean literacy is best cultivated through hands-on experience and personal interactions.
- But the technology aquariums use to bring jellyfish to the masses limit how involved audiences can be with the animals.
- Although scientists have argued technology can damage people’s relationships with other animals, it can help us reconnect with our environment too.
- Bacteria must be introduced into the tank to control jellyfish waste (ammonia) by converting it into nitrite and then nitrate.
