10. Giant Crocodile Breaks Size Record
Lolong has hit the big time—at 20.24 feet (6.17 meters) long, the saltwater crocodile is officially the largest in captivity, the Guinness World Records announced in July.
The monster reptile is the subject of the tenth most visited National Geographic News story of 2012.
Suspected of attacking several people and killing two, the giant reptile was captured alive in the Philippines' Bunawan township (map) in September 2011. (See pictures of Lolong's capture.)
The Guinness listing is based on data by experts including crocodile zoologist Adam Britton, who measured the beast in his home, the new Bunawan Eco-Park and Research Centre. (Read more about Lolong's Guinness World Record listing.)
