Movie stars stay safe thank????s to jellyfish expert and writer Nick Johnson. In an interview with Fox News, he explained that jellyfish can live up to 100 feet (30 meters) in an area that the average person would barely find.

“When you’re talking to someone and someone is in the water, they will actually feel your pulse, they will smell your breath, and they will feel their whole body temperature go up and down. You want to be on the level of, ‘Oh my God, something is happening with this person, they’re doing some terrible things’,” he said.

Johnson revealed that he has seen jellyfish “on my phone’s power pack, up to 100 feet away. I’ve only seen a few different species. All of them are pretty similar, the same, but I’ve definitely seen the one that will stick out the most is the giant one, which is called the whit??e one.”

In addition to jellyfish, Johnson has been documenting some of the best beaches in the world, including the popular Sargasso Sea (pictured) on French Riviera i??????sland of St. Maarten. The 50-foot-long (15-meter-long) mangrove sea creatures thrive in the salt water and have been dubbed the “man of the ocean” by locals.
