The term "dragon fish" typically refers to several species of deep-sea fish known for their elongated bodies and bioluminescent features. One of the most recognized species is the Abyssal Dragonfish (Grammatostomias flagellibarba), which can be found in the dark depths of the ocean. These fish have long, fang-like teeth and can grow up to 16 inches in length. Dragon fish are known for their unique adaptations to survive in extreme environments. They possess light-producing organs called photophores, which help them attract prey and communicate with each other in the dark. Their diet mainly consists of smaller fish and crustaceans, making them effective predators in their deep-sea habitat.
