I personally think that all animals think to a certain point just some more than others, take Octupuses and little sea fish, An octopus can actually unscrew a glass jar lid if he works on it a while and can even build his own house out of ANYTHING....but a simple fish only thinks "i need to eat and take care of my family" not "there might be a preditor out there to trick me into biting a fake worm"...
