Also known as the “Kings of Herrings”The Oarfish is the longes bony fish in the sea as it can reach up to over 50 feet (15meters).
It is believed that the oarfish is responsible for many of the legendary sightings of sea monster/serpents by ancient mariners and beach goers.

Bioluminescence in fish
Most deep sea possess bioluminescent organs that are normally dependent on bacteria, maintained in special cells, for the production of the light.
The bacterial light is usually produced as a result of an enzyme (often luciferase) mediated oxidation reaction in which a molecule (often luciferan) changes its shape and emits a single photon of light in the process. Luciferan is a large complex molecule that can later be returned to its original shape through a reduction reaction during which it gains an amount of energy equivalent to the single photon of light it emitted earlier. Because the essential reaction is an oxidation reaction the host organism, in this case the fish, can control the amount of light emitted by controlling the blood flow, and hence the oxygen supply, to the cells containing the bacteria.

Scientists at the Scripps Institution of Oceanography are going through the school’s library of fish, studying and photographing the collection that began in 1875. Above is a mirrorwing flyingfish.
