A large watermelon is a type of fruit known for its sweet, juicy flesh and high water content. Typically round or oval in shape, it can weigh anywhere from 10 to over 30 pounds. The outer skin is usually green with darker green stripes, while the inside is bright red or pink, filled with black seeds or seedless varieties. Watermelons belong to the Cucurbitaceae family, which also includes cucumbers and pumpkins. They are commonly enjoyed during summer months and are often served fresh, in salads, or as juice. Rich in vitamins A and C, watermelons are a refreshing and hydrating snack.
