You and your colleagues were out at sea on a Trawler boat, meticulously harvesting crabs while conscientiously releasing those that didn't meet the size regulations. As you were engrossed in your work, you felt a subtle nudge against the hull of the boat, sparking your curiosity. You paused, leaned over the side of the vessel, and gazed down into the deep, cerulean waters. Initially, there was nothing, but soon you discerned four luminous dots beneath the surface. They resembled eyes, but of something otherworldly.
