Komodo dragons fiercely compete for their prey
Komodo dragons are the biggest and heaviest lizards on Earth. Full-grown adults can reach 10 feet (3 meters) long and weigh more than 300 pounds (140 kilograms)! Most weigh about 150 pounds (70 kilograms).
These endangered giant reptiles have been around for millions of years, but scientists didn’t study them until about a hundred years ago. Wild Komodo dragons are found only on Indonesia’s Lesser Sunda Islands.
They are powerful-looking reptiles with wide, flat heads, rounded snouts, bowed legs, and huge, muscular tails. They have a clumsy, back-and-forth walk, and their yellow tongues flick in and out constantly.
