Introducing "Scream"

A student recently brought me a juvenile Great Plains rat snake.  My zoology students instantly noticed something very interesting about the pattern on the back of the snake's head:   It has a mask/hood pattern almost identical to the one worn in the popular horror movie franchise "Scream", thus giving the snake it's name.  It never ceases to amaze me how creative my students are!!  What do you think?  Can you see the hood and mask??
