Chauliodus+macouni

Summary
The [|Pacific viperfish]is a predatory fish that lives in the abyssal depths of the Pacific Ocean and Bering Sea. It is arguably the nastiest looking fish in the ocean. During the day, they are found as deep as 5000m below the surface. It swims to more shallow waters at night to find food. It mostly feeds on small crustacean, fish, and plankton, though they can overpower larger animals.

Anatomy
It is characterized as an example of [|deep-sea-gigantism], as it can grow to over one foot in length. It is characterized by its fang-like teeth, large mouth, and its large dorsal fin. They are iridescent and are typically a dark silver-blue color. They are heavily equipped with [|photophores], which generate light to help it attract prey and sexual partners. They are found as two rows on their back and contain a high concentration in their mouths





Pacific viperfish can be characterized by its large mouth, long fang-like __**﻿**__teeth and long [|dorsal fin ray] which can be as much as half its body length. They are heavily equipped with photophores which illuminate to help attract their prey.
 * Physiology**

The Pacific viperfish is in the [|phylum Chordata], [|class Actinopterygii], [|order Stomiiformes], [|family Stomiidae], and [|genus Chauliodus]. It's phylum characterizes it as a fish with a vertabre. The class Actinopterygii indicates that it is a ray-finned fish. Stomiiformes is an order of deep sea ray-finned fishes. Stomiids are generally elongated fish with black bodies.
 * Taxonomy**

The Pacific viperfish is usually found at the abyssal depths of the Pacific Ocean and the Bearing Sea. They can be found as deep as 5000 meters below the surface.
 * Ecology**

They use their photophores to illuminate light to attract their sexual partners. Little is really known about their reproduction, however it is believed that they use [|external] ways of reproduction in which they release their eggs and sperm into the water to be fertilized.
 * Reproduction**

There is not much to be said about the relationship with the Pacific viperfish and humans. We still do not know much about this species of fish. We are, however, trying to study this species anatomy and it's habitat and how it interacts with other fish more in depth.
