TORTOISE SNACKTIME: Edie the Aldabra giant tortoise snacked on carrots and lettuce at the San Antonio Zoo in Texas on Tuesday. The zoo says Aldabra tortoises are one of the world's largest tortoises, and Edie is estimated to be over 100 years old. The zoo added that tortoises are big fans of shell scratches as they can feel through their shell. 🐢 #tortoisesofinstagram #sanantoniozoo #aldabragianttortoise
