> What's the largest living reptile in the world?And the answer: saltwater crocodile. Photo credit: Discoverwildlife.comSome saltwater crocodiles are 23 feet inlength and weigh over a ton. They can be found in India, Southeast Asia, andnorthern Australia, where they're known as "salties."Before running for your life, fear not: though the saltwater crocodile proudlyboasts the most powerful bite in the animal kingdom, these large reptilesusually stay away from humankind. These fearsome predators turn mostly to largeland animals for their dinner, ranging anywhere from crabs and fish to birds,turtles, pigs, or buffalo. Saltwater crocodiles have inhabited brackish andfreshwater regions of eastern India, Southeast Asia, and northern Australia formillions of years (their first appearance was around 240 million years ago, inthe Mesozoic era – that predates some dinosaurs!). To hunt, the "saltie" poses near the shoreline, remaining virtually invisiblejust at the water's edge, lurking underwater for up to an hour. When potentialprey leans down to the water to drink, SNAP! The saltwater croc acts quickly,and with a mouthful of 5-inch teeth, these predators don't shoot to miss.Interestingly, they've also coined an attack method amicably called the "deathroll" – the croc pulls its prey underwater and spins to disorient it (maybe theworld's worst swirly). Saltwater crocodiles have a lifespan that can reach up to 70 or 80 years. Afterfacing threats to their population in the early 1960s from hunting by humans,these prehistoric creatures have made a comeback to last the ages.
