Theresa Solis shot this photo while walking along the Santa Monica Pier with her daughter.
"The pier is one of my favorite places in SoCal and the blue color of that wall was so striking," she said. "I thought the shell would really stand out against it.
The seashell was sent to Solis as part of an Instagram initiative called the Traveling Shell Project. The project initiator, @seamerias, sent shells to volunteer Instagram users and asked them to take photos of the shells in whatever setting they like. After Solis took her shell photo, she tagged it #seameriastravelshell and passed it to another Instagram user.
Solis used an iPhone 6 to make the photo on Feb. 3.
