In its 37th year, Shark Week is the Discovery Channel's annual weeklong slate of shark-related programming. This year's event kicked off Sunday, July 20, with "Dancing With Sharks," an inter-species dance competition hosted by returning "Dancing With the Stars" frontman Tom Bergeron.

Shark Week opens with “Great White Sex Battle.” Watch three consecutive premieres starting at 8 p.m. ET on Discovery.

Have you noticed the sharks are late this year? Shark Week 2025 finally splashed onto our screens this past Sunday, just in time for the hottest days of the year — the perfect time to sit inside with the AC blasting while you watch hours of new shark content every night, or go take a dip in the water yourself (if you’re brave enough).

Discovery Channel’s “Shark Week” kicks off with a unique twist this year: “Dancing with Sharks.” Hosted by former “Dancing With the Stars” host Tom Bergeron, the show features scuba-diving shark handlers performing underwater dances with hammerhead sharks.

Tom Bergeron talks hosting Shark Week's "Dancing With Sharks" and the "sad" trophy. "That's the same reaction I had with the 'DWTS' trophy."
