What to stream: Set course for shark-infested waters with these movie picks

It’s the most wonderful time of the year: Shark Week! The ever-popular weeklong programming event on the Discovery Channel has been delighting shark enthusiasts now for 37 years. Twenty new original programs will be premiering from July 20 to July 26, so be sure to tune in for shows like “Dancing with Sharks” (hosted by Tom Bergeron), “Frankenshark” and “Battle for Shark Mountain.”

And, because it’s summer — and summer means shark movies, thanks to the original blockbuster, “Jaws” — you can also cue up a wet and wild movie marathon to make up your own cinematic Shark Week in addition to the regular Discovery programming.
