Shells from Coquina Beach on Longboat Key February.23.2014. We took a long drive to Longboat key for a tiny Wentletrap. What I love about Longboat key are the darker shells than on Honeymoon. Little black scallops and beautiful colored coquinas. I found lots of minis and even a purple sea whip. But the best is the smallest, a tiny Wentletrap (the bottom of the second picture.) Great day for tiny shells!
