I like to descend into the Patapsco Valley to experience its natural heritage through encounters with the more unusual animals that share the earth with us. When my children, Kelly and Julia, were young, the three of us were walking the winding path of Patapsco State Park on our way to the river. There in our path, was a snake with a “hog nose,” (aka a “hognose snake”).
This strange creature proceeded to give Kelly and Julia a lesson in the wonders of biological evolution:
First she (the snake) tried to get away. Next, when I blocked the path of escape, she flattened her head (to look like a rattlesnake) and struck at my foot, and finally, when the humans were not deterred, she rolled on her back to show she was dead.
And perhaps most amazing of all (and perhaps not that adaptive), when turned right-side up, she turned up-side down again–to show that she was really dead!
