Anyone home? Watch giant monitor lizard claw at window of Florida home

Lizards come in all shapes and sizes, most of them of the smaller nature. 

What Joycelyn Penson encountered while visiting her son's home in Orland was not small. Penson spotted (and nabbed video of) a gigantic, human-sized lizard big enough to take on an alligator. 

In the video initially shared to her Facebook page, Penson wrote: "OMG! LOOK AT THIS! My son lives in Orlando, Fla. Really, it’s Apopka, Fla. Look at what came to pay him a visit today! It’s a Tegu lizard!"

The lizard, most likely a monitor lizard, is seen in the 40-second video trying to literally knock at the home's door and scratch at it by finding a way to get into the house while standing on a windowsill.

Monitor lizards are among the largest on the planet and sport long necks, powerful tails and claws, and well-developed limbs. The adult length of extant species ranges from 8 inches in some species, to over 10 feet in others.
