Polyipnus limatulus
Polyipnus limatulus is a small deep‑sea lanternfish (family Myctophidae) that inhabits the mesopelagic zone of open oceans. It grows to about 7 cm (2.8 in) and is bioluminescent, making it more of a scientific curiosity than a sport or food fish. Anglers rarely target it, but it can be encountered when night‑trolling in deep water.
