This is the first live Moon Snail I've encountered. That doesn't mean a whole lot, as they are not particularly rare or anything. It was caught on the beach too far above the receding tide line to be taken back out to sea. It found a small tide pool on the sand and began to undulate its fleshy "foot" in a circular manner, pulling itself under the sand to stay moist until the next high-tide. Just beautiful in its textures, colors, and exquisite movement.
