Which of the most feared predators on the planet packs the most powerful bite? Expert Brady Barr finds out.

As National Geographic’s resident herpetologist, Dr Barr is the first person to ever capture and study all 23 species of crocodilians in the wild. With one-third of all crocodile species endangered, Dr Barr’s extraordinary achievement brings much needed attention to their plight.

Dr Barr made worldwide headlines last year when he wore a custom-designed crocodile suit to get up close and personal with these cold-blooded denizens of the Nile. This year, he’s gone one step further, creating a life-like hippo suit to get close enough to these deadly African giants to scrape the sweat off their backs.

With the new season of his series Dangerous Encounters, join us for an unforgettable National Geographic experience as Brady Barr recounts his most recent adventures in the field, including a near death experience in remote Indonesia.

Eventually after some intense searching, Brady finds his first eel and his capture results begin to improve.

Along the way Brady will encounter venomous snakes and swarming piranhas, and the rare Suriname Toad.

But before he ventures into squid territory, he gets an idea of what he's up against: Eight powerful arms, each lined with suckers containing sharp teeth, two long tentacles that launch out to capture prey, and a beak that can bite more powerfully than a crocodile - Brady finds out what an ultimate predator the Humboldt can be. The team heads to Santa Rosalia Mexico to carry out their mission, where fishermen haul up 10,000 squid a day. Brady plunges into the Sea of Cortez and goes head to head with the Humboldt.

The fish has evolved over millions of years perfecting this body design, yet scientists are not sure exactly what the saw is for, or why this fish needs teeth outside its mouth. Dr. Brady Barr will stick his nose into this mystery - to find out why the sawfish has a saw. To find out, Brady will turn to two other ancient oddballs of the fish world- the white sturgeon and its close relative, the paddlefish -to see if their long snouts can shed some light on the workings of the sawfish's saw.
