Coryphaenoides

Coryphaenoides is a genus of deep-sea fish belonging to the Macrouridae family, commonly known as grenadiers or rattails. These fish are adapted to cold, high-pressure environments deep beneath the ocean surface, often found at depths greater than 1000 meters. They have elongated bodies with tapering tails and large heads, and many possess bioluminescent features. Coryphaenoides species play a vital role in the deep-sea ecosystem, feeding on invertebrates and smaller fish, and are of scientific interest due to their adaptations to extreme environments.
