Sharks vs. Dolphins: Face Off

“Reel them in,” marine ecologist Dr. Mike Heithaus says with a laugh. No, Shark Week titles don’t get much grabbier than his, Sharks vs. Dolphins: Face Off, which premieres tonight at 10 p.m. on Discovery. As it suggests, the two species are at odds more than we suspect, and the hour looks at not only likely attack scenarios — see one in the sneak peek above — but also the strengths and weaknesses of each.
