The deep sea hosts a parade of creatures that seem plucked from science fiction, each a marvel of evolution. Imagine the fangtooth with its disproportionately large teeth, the delicate Dumbo octopus with its ear-like fins, or the gulper eel capable of swallowing prey much larger than itself. These extreme adaptations are essential for finding scarce food and avoiding becoming a meal in this high-pressure, low-resource world.
