Platytroctidae

The tubeshoulders are a family, the Platytroctidae, of marine smelts. They are found throughout the world, except for the Mediterranean Sea. Tubeshoulders live at moderate depths of 300 to 1,000 m (980 to 3,280 ft), and some have light-producing organs. They are generally small to medium fish, ranging from 9 to 33 cm (3.5 to 13.0 in) in length.[2]
