Researchers investigate whether orcas have begun hunting great white sharks off the coast of New Zealand.

Scientists set out to learn how great whites defeated a super-predator.

Dr. Riley Elliott returns to Australia's Norfolk Island with underwater cinematographer Kina Scollay to see what happens when the island's tiger sharks go head-to-head with migrating great whites over an unusual food source: cow carcasses.

Follows scientists searching waters north of New Zealand for giant mako sharks, discovering a population that might be making a comeback despite being endangered elsewhere.

Shark expert Kina Scollay and his elite team return with a unique one-person submersible, the Mechashark, to a top secret location off New Zealand attempting to do something that's never been done: locate a great white shark mating ground.

The Discovery Channel's Shark Week, first broadcast on July 17, 1987, is a weeklong series of feature television programs dedicated to sharks. Held annually, normally in July or August, Shark Week was originally developed to raise awareness and respect for sharks. It is the longest-running cable television programming event in history. Now broadcast in over 72 countries, Shark Week is promoted heavily via social networks like Facebook and Twitter.
