They are supposed to be prepared to handle most anything, yet a harmless lizard managed to scare the daylights out of U.S. Secret Service agents preparing a residence for President Obama’s trip to Thailand.
Thai officials, however, reassured the U.S. Secret Service that the massive lizards found on the Government House grounds were not the dangerous Komodo dragons, but the harmless, lazy water lizards.
Both belong to the monitor lizard family and can grow up to 200 pounds and ten feet long.
While not as aggressive as Komodo dragons, water lizards can be defensive when threatened and use their tail, claws, and jaws when fighting off predators.
