Man films himself swimming with millions of jellyfish

Ongeim’l Tketau, a marine lake located on Eil Malk in Palau in the western Pacific, is filled with millions of golden jellyfish, attracting tourists who pay $10 a day to swim or snorkel with them.

John Hawkins, an English teacher from Canada, recently visited the 100-foot-deep lake, capturing his snorkel session among the slow-moving golden jellies. These Mastigias papua etpisoni carry a sting that is "mild and often undetectable," according to the Coral Reef Research Foundation.

"This has given rise to the myth that the jellies have lost their ability to sting," the foundation says. "However, you may feel their tingly sting if an oral arm comes in contact with sensitive skin like that around your mouth."

Indeed, the risk of humans harming the fragile floating fish is greater than feeling their sting. Scuba diving is not permitted, and swimmers and snorkelers are advised to move slowly, use clean snorkel gear and not apply sunscreen directly before entering the water to help preserve the 13 million jellies for snorkelers like Hawkins to enjoy.
