The kraken is a sea monster with long, snakelike arms. This amazing creature may have been inspired by a living animal--the giant squid of the deep ocean. The kraken also tells us something about the minds of sailors long ago. As they ventured across vast oceans for the first time, they must have wondered with fear and awe what creatures lurked below.
