We don't like to think of ourselves as prey--it is a lessening thought--but the truth is that in our arrogance and so-called knowledge we forget that we are not unique. We are part of nature as much as other animals, and some animals--sharks, fever-bearing mosquitoes, wolves and bear, to name but a few--perceive us as a food source, a meat supply, and simply did not get the memo about how humans are superior. It can be shocking, humbling, painful, very edifying and sometimes downright fatal to run into such an animal.
