The Green Sea Turtles which hang out in front of my house are so accustomed to snorkelers that they completely ignore us. The one in the middle photo swam right up to me this morning, then pushed me aside with one flipper and swam past.
I'm a guy who likes to get out into the ocean several times each week and interact with the creatures I encounter there. I often swim with dolphins, sharks, rays, and whales. Check out my photos on my website: www.TropicalLight.com
