  Barreleye - Wikipedia, the free encyclopedia
Barreleyes, also known as spookfish (a name also applied several species of chimaera), are small, deep-sea, odd-looking osmeriform fish comprising the family Opisthoproctidae.
They are presumably solitary and do not undergo diel vertical migrations; instead, barreleyes remain just below the limit of light penetration and use their sensitive, upward-pointing tubular eyes—adapted for enhanced binocular vision at the expense of lateral vision—to survey the waters above.
The fertilized eggs are buoyant and planktonic; the larvae and juveniles drift with the currents—likely at much shallwer depths than the adults—and upon metamorphosis into adult form they descent to deeper waters.

The (Studies of the rules for forming admissible words) morphology of the Opisthoproctidae varies between three main forms: the stout, deep-bodied barreleyes of the genera Opisthoproctus and Macropinna; the extremely slender and elongate spookfishes of the genera Dolichopteryx and Bathylychnops; and the intermediate fusiform spookfishes of the genera Rhynchohyalus and Winteria.
Barreleyes inhabit moderate depths, from the (additional info and facts about mesopelagic) mesopelagic to bathypelagic zone, ca.

To better serve their vision, barreleyes have transparent to translucent heads; this presumably allows the eyes to collect even more incident light.

 Encyclopedia: Barreleye
The distribution of some species coincides with the isohaline and isotherm layers of the ocean; for example, in Opisthoproctus soleatus upper distribution limits coincide with the 400 metre isotherm for 8°C. The pelagic zone is the part of the open sea or ocean comprising the water column, i.
An isotherm is a line of equal or constant temperature on a graph, plot, or map; an isopleth of temperature.
What little is known of barreleye reproduction indicates they are pelagic spawners; that is, eggs and sperm are released en masse directly into the water.

Barreleyes and Blacksmelts are some of the few fish known to eat gelatinous midwater animals such as salps(below).
Barreleyes have their huge eyes permanently focused to look straight up.
Snipe Eels use their elongated jaws to catch shrimp, perhaps by entangling shrimp antennae.

Several species of fish and squid utilise bioluminescence as counterillumination, making them more difficult for creatures below them to see.
Animals that do this include the Bobtail squid, marine hatchetfish, barreleye, and cookiecutter shark.
Bioluminescence is used as a lure to attract prey by several deep sea fish such as the anglerfish.
