? Did you know: An elephant's age can be estimated by examining molar sequence and wear! Asian elephants have six sets of teeth. Each successive set is larger, more complex and lasts longer than those previous. As a result, an elephant's skull grows throughout its lifetime to accommodate the new and ever-larger teeth.
Meet the Zoo's elephants and their keepers at the daily 11 a.m. training demonstration. PLAN YOUR VISIT: https://nationalzoo.si.edu/visit/daily-events.
