I’m told that this is a snail. We happened upon two of them. I went to macro setting. I shot and shot. I got one image… not a very good one. Hey, it’s a snail and it wasn’t moving. But my dive buddy wasn’t staying, and I can’t ‘leave my wingman.’ You can’t exactly return to a random spot in the sea. So who knows if I’ll ever see this again. It’s not like a walk in the park. We’ve been on this reef back and forth many times now. Each dive is unique. Come to think of it, my dive buddy is like my wife, they never stop or look back. It’s entirely up to me to keep up or be lost. It’s amazing how I got the skill to shoot and scoot.
