more SAN DIEGO, CA - JUNE 14: In this handout image provided by SeaWorld San Diego, five African-spurred tortoises, also known as sulcata tortoises, enjoy time on the grass at SeaWorld San Diego June 14, 2012 in San Diego, California. The adult, named Buster, is about 20 years old, and the young ones are just under a year old. Sulcata tortoises are native to northern Africa and can live to be 100. Sulcata tortoises are common in pet stores, but are often relinquished by their pet owners, who aren't prepared for how big they get (they can weigh up to 150 pounds). SeaWorld guests can see Buster and friends near SeaWorld San Diego's Animal Connections area. (Photo by Mike Aguilera/SeaWorld San Diego via Getty Images)
