The aquarium club at a public high school in Ehime Prefecture has developed a prototype for a cream that prevents jellyfish stings, with a goal of releasing the product in February with help from a private company.

With products to prevent jellyfish stings still a rarity in Japan, members of the Nagahama High School club in Ozu will start by promoting their creation, named Jelly's Guard, primarily to surfers.

While researching the symbiosis between clownfish and sea anemones, club members learned that the mucous coat of clownfish, with its high concentration of magnesium, prevents them from being stung by sea anemones.
