Galeophobia (also known as selachophobia) is defined as the irrational fear of sharks, but rationalizing it won’t be very hard after this. The Smithsonian posted a video today as a preview for their upcoming show, Secrets of Shark Island, that shows hundreds of sharks of varying species sharing the deep blue waters. The special profiles a location 250 miles off the coast of Mexico called the Revillagigedo Islands, where giant manta rays grow to be 22 feet wide and massive shivers of sharks feast on schools of bonito fish.

Check out a few screenshots from the clip below, and head over to Smithsonian to watch the terrifying yet beautiful footage—and to see when the full program will be available in your area.
