The small jellyfish-like creatures have a deep blue hue and sails that allow them to glide across the ocean’s surface. Once it reaches the beach, it loses its pigment and dries out. However, don’t worry, they do not sting humans like jellyfish do.

As the ocean warms in the spring, more nutrients become available in the water, leading to a significant reproduction of organisms. Berera Bererassaid Wagner. Human-induced climate change could also contribute to the increase in numbers, he said, as the oceans get warmer.

“Climate change will accelerate these processes because it gets warmer faster and nutrients increase,” Wagner said.

Sailor on the Wind is a member of the jellyfish family, but is not a true jellyfish, he says. Each blue “raft” is made up of multiple organisms with specialized functions such as feeding and reproduction. Before they attach to the surface, they live underwater as tiny creatures known as jellyfish, Wagner said.
