巨口鱼, also known as the Giant Mouth Fish, is a species of deep-sea fish recognized for its enormous mouth and unique feeding habits. This fish can be found in the depths of the ocean, where it uses its large mouth to capture prey, including smaller fish and plankton. Its distinctive appearance helps it thrive in the dark, deep-sea environment. The scientific name for 巨口鱼 is Megachasma pelagios. It was first discovered in 1976 and is part of the filter-feeding group of fish. This species is relatively rare and not well-studied, making it an intriguing subject for marine biologists and ocean enthusiasts alike.
