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.


  • Dangerous Encounters: Snakebot
    Pairing a prosthetic limb with a robotic bomb disposal platform, Brady Barr tests this snake-removal device – a Snakebot – on properties invaded by two of the world’s most intimidating snake species.
  • Dangerous Encounters: Man-Eaters
    A massive one-ton crocodile is terrorising villagers on the banks of Lake Victoria. Brady Barr sets out with villagers in dugout canoes to find and capture the man-eater before it kills again.
  • Dangerous Encounters: Shark Bite
    Most shark attacks on people are committed by just three species: the tiger shark, the bull shark, and the great white. Brady Barr attempts to determine which one has the deadliest bite.
  • Dangerous Encounters: Extreme Fish
    From the rapids of the Hells Canyon river gorge in Idaho to the remote waters off Andros Island in the Bahamas, dive in with Dr. Brady Barr as he embarks on a mission to better understand one of the strangest looking fish on the planet: the smalltooth sawfish. An ancient cocktail of a creature -it fuses a shark's tail with a rays flattened body. But the thing that's truly unique about this fish is its long snout studded with needle sharp teeth - the saw. 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. Can Brady piece these clues together to complete his investigation, and can he find an adult in the wild?
  • Dangerous Encounters: To Catch A Hippo
    Strong, fast and semi-aquatic, the hippo is one of Africa's biggest wildlife management challenges.1 The use of tranquilizer darts is nearly impossible, as a threatened hippo will dart straight for the nearest body of water and dig in. If the animal has been tranquilized, it can drown before the drug wears off, hampering the efforts of wildlife specialists.2 But Brady has a new idea-he wants to see if a net will hamper the hippo enough to keep it out of water and make the capture safer. First, he pays a visit to Florida to test his idea out on wily Florida swamp gators-and it's a complete success. He then packs up his nets and heads for Malawi, where he'll learn the ins and outs of the net gun already in use on smaller game. After an unexpectedly intense pursuit of a slippery warthog, the team is prepared to tackle the big game-the hippopotamus. With ground and air units in place, the search begins to find and safely capture a hippopotamus and see if Brady and his team can rewrite the rules of hippo capture!
