Ocean Surprise

You wake up, make your morning coffee, and head out the door to the beach. You feel really lucky to have found such a good deal on your house, especially since it’s 50 feet from the surf. Your feet splash through the water when it laps against your toes. The seagulls scream for food as they swoop above you. Your coffee dances over your tongue, eliciting a groan of pleasure as the caffeine wakes you up. Out of the corner of your eye, you see something move against the rocks in the water. Hand to forehead, you shade your eyes and gasp. What do you see?
