Shark Week

After a wave of mauled marine life washes ashore in New York, conservation biologist Dr. Craig O'Connell launches an investigation to find the culprit. When it leads to an old nuclear dumping ground teaming with great whites and makos, he is left with the chilling theory that the predator may be radioactive. A deeper dive reveals an unexpected hotspot for massive makos off the coast of the Hamptons, suggesting that these waters may be hiding something even bigger beneath the surface.

How far will people go to fuel their fascination with sharks? For four devoted shark "fin-atics," their obsession shapes every aspect of their lives. From a dentist who spends every spare moment searching for life-size shark replicas that overwhelm his home to a woman who insists she has a special connection with her shark "boyfriend," and a world-record holder covered in shark tattoos, this special explores how their daily routines, relationships, and finances revolve entirely around the apex predators they can't live without.

Great white sharks are pushing farther up the East coast than ever before and in far greater numbers leading to close encounters, forcing beach closures, and leaving locals wondering where the next attack could happen. Now, a daring team of shark scientists race to install high-tech receivers and tag as many great whites as possible before another harrowing incident rocks the country.

The physics behind the thresher shark's devastating tail strike has long remained a mystery…until now. For the first time ever, the discovery of a shallow-water feeding ground has made observing this behavior possible. Now, shark scientist Dr. Craig O'Connell and marine biologist Aliah Banchik dive into the direct line of fire as they attempt to reveal exactly how these predators use their tails to stun and kill.
