Dr. Gary West had been examining Ali the tortoise when the magical selfie was snapped.
“He approached me with curiosity and seemed to look at himself in the phone when I held it out in front of us, so I snapped a picture," West said in a previous 12 News story.
It was the giant tortoise selfie seen around the interwebs last year, and what better way to celebrate National Selfie Day than sharing the one-of-a-kind photo so people can enjoy it all over again?
"Of course, National Selfie Day wouldn't be complete without the famous Tortoise Selfie," the zoo wrote on Facebook.
And we'd have to agree. You can't possibly celebrate this day without seeing Ali and his amazing selfie.
