Join Dr Brady Barr as he travels the world in search of massive crocodiles. His mission is to capture a 5.5-metre long monster to beat his biggest catch to date.

Dr Brady Barr is on a mission to find another of America's alligators: the alligator snapping turtle.

Something is blinding American Crocodiles living in Costa Rica's Tarcoles River and National Geographic herpetologist Brady Barr is on the case. Turns out-- the Tarcoles River is one of the most polluted waterways in South America. Could deadly pollutants be the smoking gun or is something even more sinister at work? To solve the mystery, Barr teams up with scientific heavy weights Thomas Rainwater, a toxicologist at Texas Tech, to determine if any nasty toxins might be responsible and Nick Millichamp, a veterinary ophthalmologist specializing in eye diseases in exotic species, to determine if the problem is biological. Together, they head into the murky river to catch crocs and gather clues with the hope of solving the mystery.

Great white sharks, Nile crocodiles and even the Tyrannosaurus Rex - all colossal beasts feared for their terrifying bites. But which animal has the most monstrous bite? To find out, Dr. Brady Barr uses a special bite meter to measure each animal's bite force and break his all-time record. He wrestles a 2.4-metre nurse shark and carefully crawls down a red wolf's burrow, tempting it to take a bite. From the air to the ocean, Brady looks at creatures big and small and finds super strength in some surprisingly small packages. A Tasmanian devil exerts almost the same bite pressure as a grey wolf more than six times its size. With the help of other researchers, Brady even examines the bite force of the Tyrannosaurus Rex - the largest carnivore thought to have ever roamed the Earth. The results: a T-Rex could exert 2,721 kilograms of bite force - the equivalent to being crushed by a Hummer. However, the Tyrannosaurus Rex has some competition for "King of Bite Force" title. Brady finds a croc whose mouth is so powerful, it has the strongest bite force of any living animal ever recorded.

In this episode, "big is better." A $50,000 reward is offered by The New York Zoological Society for what would be one of the biggest draw cards in the animal world - a healthy snake over 30 feet long. Brady goes into sleuth mode studying a mind-blowing collection of old photos of giant snakes. What is certain is that there are only four species that could possibly get that big! The Indian Python Snakes are part of the culture in India… a country known for its snake charmers. Brady consults with snake men and sees an array of deadly reptiles before trekking out to find a giant Indian Python. It's nesting season for the snakes and he may find more than he bargains. Dino Snakes To find the largest snake ever is to journey back in time. Brady heads to an excavation to unearth the earliest snakes… 55 feet long and weighing half a ton. Singapore Sewer Monsters Several times a week Singaporean police are called out to collect reticulated pythons that are overrunning the island. Many are in the sewer system. Brady gets the scoop. In nearby Indonesia locals claim to have a reticulated python that is over 40 feet! Brady is ever-skeptical but the snake must be big and he must check it out. The Anaconda There's one last snake that could possibly lay claim to the reward. Anacondas keep growing throughout their lives and some old snakes have been known to eat cattle! Brady wrangles baby and giant anacondas and again checks their squeeze and bite strength with his special devices. He also checks the accuracy of a claim that the longest anaconda ever captured was 9.75meters… that's 32 feet!

This episode begins with Brady Barr in the snow-covered wilderness. "Cold as hell out here…and it's about to get as scary." Brady is tracking one of the world's largest land carnivores. Weighing in at nearly half a ton, the female grizzly bear - with cubs - is one of the most dangerous animals on the planet. And Brady is about to make one VERY angry… he'll enter the den of a giant grizzly mom and wake it from hibernation! In Africa, Brady crawls into a den with no idea what he'll get… cobra, scorpion, puff adder, mamba? The den belongs to the alphabet's first animal… the aardvark. Seemingly a mild-mannered animal it digs burrows - but a deadly array of creatures wait to take over. Near the artic, imagine a highly intelligent boneless predator with eight 8ft arms, more than 2,000 suckers and a savage parrot like beak. This is the world's largest octopus and Brady will find one of these giants and wrangle it to the surface. Next Brady dons special respiratory gear, not to go underwater, this time to avoid getting the bubonic plague! He enters a Hyena's den and while Hyenas have one of the strongest bites on the planet the danger of exploring their underground homes doesn't end there. Last, but not least, brave Brady, with help from a robotic friend, enters the den of the American Croc to map the labyrinth of a man-eater. Each tighter and tighter turn is a heart pounding moment.

Brady captured the 4 biggest salamanders and rated their size, survival skills and their overall sliminess to determine the King of Amphibians.
