Pacific viperfish

The Pacific viperfish (Chauliodus macouni) is a species of deep-sea fish found in tropical oceans. It belongs to the genus Chauliodus and is known for its long, fang-like teeth that protrude from its jaws, used to capture prey. These fish also possess luminescent organs along their sides, which may help attract other fish for food. The Pacific viperfish is the largest species of viperfish, reaching up to 30 centimeters (1 foot) in length. Marine bioluminescence, the production of light by marine organisms, is a common phenomenon in the deep sea and serves various functions, including attracting prey.123
