Jellyfish are graceful, delicate and mesmerising life forms that have inhabited the world’s oceans for millions of years. Pietro Cimmino explores the characteristics of jellyfish, their role in marine ecosystems and their importance in our scientific future.
Nanomia bijuga is part of a group of organisms, known as physonect siphonophores, a group of chain-like hydrozoan predators and a relative of jellies, anemones and corals.
In some tropical waters like the Florida Keys mangrove forests, for snorkellers to stay safe, it’s not enough to not touch anything. It may not be a good idea to enter the water in the first place.
That’s because sometimes it seems that the water itself can sting, causing rashes on a snorkeller's skin.
The real culprit is not some mutant strain of water molecules. Rather, it is a species of upside-down jellyfish that lives on the ocean floor. Called Cassiopea xamachana, this jellyfish can also be found in places like the Caribbean Sea and the Gulf of Mexico.
