Snorkeling and Galapagos Green Turtles

We went snorkeling in a cove to look for turtles. I got separated from the larger group as one of the swimmers told me a turtle was just behind us. I did find it. It was smallish and down on the bottom almost disappearing in the swirling sand. I swam back and forth and was getting frustrated to I headed to shore. Just then, I swam over a huge adult in clear water eating plants and algae! It couldn't care less about me but I did think I shreiked for joy though the snorkel. I floated above it just watching for the longest time. We both went back and forth with the current from the waves. I only stopped when I realized the others were getting back in the pangas. The turtle was so graceful. I know I've been told they are in the water, but I was in awe. Another wonderful encounter.
