An octopus has sensitive suckers on its arms. When they touch an object, specialized receptors help the animal detect some chemicals—a kind of taste that works through touch. So “tastes with its tentacles” conveys the general idea, but more precisely this is chemical sensing by the suckers; it does not mean the arms smell things from a distance.
