• A close up view of a elephant's eye in Chiang Mai, Thailand. Asian elephants have rather poor vision capable of seeing clearly only at very short distances -- up to about only 15 feet. In wooded areas, elephants can lose sight of each other, so they emit rumbling purrs in order to keep in touch. Asian elephants are strong, social, and intelligent.
