At 54 years, Mary is the life of the (pool) party. 🐘 Fun fact: elephants use their trunks to drink, but the water doesn’t go all the way up the nose like a straw; instead, the elephant sucks water only part way up the trunk, curls it toward its mouth, tilts its head up, and lets the water from the trunk pour in. #skipthestraw #poolparty #sandiegozoo
