The difference lies in the appearance and taste. 1. Different appearance: Oranges are larger than navel oranges, darker in color, smooth surface, and juicy pulp; navel oranges are relatively small, slightly round in shape, with thin and smooth peel, and an obvious depression on the top of the fruit, called a "navel". The pulp has little juice.

2. Different tastes: oranges have a rich taste, moderate sweetness, and crisp texture; navel oranges have a more delicate taste, high sweetness, and soft and juicy pulp.
