Blueberries have a lush flesh and thick skins.  The blue pigment in their skins make blueberries a powerful antioxidant. The smaller more intensely flavored wild blueberries are more nutritious than their large farmed relatives.

Blueberry and Huckleberry are often used interchangeably, but the fact is that the Huckleberry belongs to the genus Gaylussacia, while the Blueberry belongs to the genus Vaccinium.  Other differences are that the huckleberry has 10 large seeds surrounded by a covering or pit while the blueberry has two or three times as many seeds as the huckleberry, but they are small and not noticeable when eaten.  Blueberries are cultivated, while huckleberries are not.
