Spots, or marks, are small, distinct areas on a surface that differ in color or texture from their surroundings. They can occur naturally, such as freckles on skin, or be caused by external factors like stains on fabric. Spots can vary in size, shape, and color, and they often serve as indicators of certain conditions or characteristics. In the context of animals, spots can be a form of camouflage or a means of attracting mates. For example, the leopard has distinctive spots that help it blend into its environment, while the peacock displays colorful spots on its feathers to attract partners.
