   The mind of an elephant should not be underestimated. They are brilliant creatures blessed with both excellent memory and artistic talent. Elephants each consume approximately 495 pounds of vegetarian food a day. They spend about 16 hours a day eating, but must walk about 4 miles a day in search of food. This extreme need for food is a huge burden to the elephants. The average elephant lives approximately 70 years, and its sharp memory allows it to remember locations where it has found food as long as thirty years earlier, even as a baby.
   In an elephant’s travels, they come across other elephants also looking for food. Some elephants are friendly, and some are not so nice. Elephants remember every elephant they have ever met. They can even recognize an elephant they perhaps haven’t seen for thirty years. They immediately remember whether this elephant is a threat or a potential friend.
   When elephants are not searching for food，they sometimes produce art in the sand with their trunks. They seem to enjoy just relaxing and painting in the sand. One day, an elephant zoo-keeper noticed this and gave an elephant a paint brush filled with red paint to see what it would do. The zoo-keeper put a canvas on the ground to see if the elephant would paint on it. Sure enough, it did, and since then elephants in most zoos have been given paint brushes, paints, and canvases. The resulting abstract art has been sold for high prices around the world. The funds go to support feeding the elephants in the zoos. Most felt that the elephants were only capable of painting abstracts. However, they have been trained to paint trees, flowers, and other items in nature. This has enabled us to understand “elephant genius” even more.
