| Naturally, in a group of animals as
diverse as the snakes, and with so many varied enemies, there are numerous
defensive reactions and devices. There is, however, one general pattern of
behavior. In the presence of suspected enemy the first reaction is to try to
escape observation; if this fails, the next resort is the flight to some
inaccessible retreat, but if this is not possible, or is circumvented, various
kinds of intimidatory gestures and warning devices are brought into play; in the
last resort the snake attacks. This pattern varies with the circumstances; some
stages may be omitted or combined unpredictably whilst; some notoriously
irascible species may dispense with all the preliminaries and attack almost at
once, though seldom or never without some provocation. Amongst the factors that increase aggressiveness a A. the snakes combine all the previous three steps. B. the snakes give up all the previous three steps. C. the snakes follow all the previous steps one by one. D. the snakes reverse the order of all the previous steps.
