Discovery’s “Shark Week” has a rival — National Geographic’s “SharkFest,” which also has hours of sharky content. There's also the unconnected shark horror comedy “Hot Spring Shark Attack” and a movie earlier this summer that added a serial killer to a shark movie — “Dangerous Animals.”

Dancing With Sharks” is a reality dance competition for Discovery Channel’s Shark Week pairing dancing divers with real sharks and hosted by Tom Bergeron.
