shortnose lancet fish
Quick Summary
The shortnose lancet fish (Alepisaurus brevirostris) is a species of deepwater marine fish found in the Atlantic and south Pacific oceans. Lancet fish are characterized by their elongated, slender bodies, a tall dorsal fin, and a large mouth with sharp, fanglike teeth. They are voracious carnivores, preying on various fish and invertebrates. These fish can grow up to about 1.8 meters (6 feet) in length. Deep-sea fish, in general, have evolved unique adaptations to survive in extreme ocean depths, including large mouths and, in some cases, luminous organs.123
