Our PF fence lizards are superbly adapted to the local oaks and they disappear as soon as they stop moving.
They're using a passive defense known as disruptive coloration. Disruptive coloration is designed to break up your outline so you look less lizardy, fishy, snakey, etc.
Stewie the cornsnake uses a similar plan, as did the US Navy (Navy 1, Somali pirates 0!) in World War II.
Back then, some warships in the Pacific were painted with a zigzaggy, almost zebra pattern to break up their shippy outline when viewed at a distance in heaving seas.
This fat (pregnant?) fence lizard was making the best of a dilemma. When I came walking up, she was on the green barn siding and stood out like the bullseye on a target.
Instinctively she stood still, but then something clicked and she moved to the nearest object that allowed her passive defences to operate.
She hasn't vanished, but she's doing a pretty sweet job of being the sledge.
In other news ...
Last night and most of this morning was pretty stormy with the red tornado watch box shifting all around and over us. The Suwannee and her tributary the Santa Fe are flooding and the pulse of water which began in South Georgia weeks ago is approaching my end of the Suwannee.
After this post, I'm heading out in the JEEP to see if I can bring you a few pics of the floodwaters, or at least an "up" Suwannee.
Stay tuned ...
