Jumping lizard tail!

On Monday when I opened the garage door in preparation for heading to my platelet donation appointment I noticed a lizard sitting near it. This lizard was smaller than the one we saw in our house last week. Apparently the noise and motion of the garage door rising scared it so much that its auto defense mode kicked in and its tail came off! The tail didn't just lay there or wiggle back and forth, it actually jumped and hopped and flopped around like it has having a seizure while the lizard remained relatively still. It was so weird looking! I can easily see how that would be distracting to a predator.
