This is a picture from the beach on Sanibel Island, Florida. There was a very low tide that exposed a sandbar so that it was completely dry. On the sandbar, you could see Olive shells (probably oliva sayana, or lettered olives) alive and moving around. Moving around fairly quickly for something that’s cousin to a snail. Apparently, they’re one of the fastest burrowers among the snails. As they moved, they made little patterns in the sand which you see here, along with the Olive’s themselves, and their little siphons, which they would stick up into the air as if to say, “Hey, what’s going on here?” I’ve been going to Sanibel for 24 years and have never seen Olive’s moving around like this, which just goes to show you that Mother Nature always has something up her sleeve.
