Tonight on the Discovery Channel, scientists explore great white migration patterns, shark attack survival tips, and an elusive deep sea beast. Stream Shark Week through Saturday, July 26.

Now a bonanza of viewership, the 37-year-old event that launched as a meager presentation of 10 basic programs and has also courted detractors over the years.

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.
