Something so unusual that it must be from some unfamiliar place is exotic. An exotic pet might be a panda, instead of a hamster. An exotic trip might be a journey to the Galapagos Islands, instead of to Orlando's Sea World.
Animals and people, or sensory things like food and smells, are often called exotic when they are from far-away lands. In the 16th century, exotic came into use — from Latin and Greek words for "foreign," which came, in turn, from exo-, meaning "outside." By the 17th century it was also being used to describe things that are striking or unusual. Even when the words strange and alien are sometimes used as synonyms.
