Ascallion

Ascallion, also known as scallions, were nomadic predatorial fish that inhabited the warm and temperate oceans of Faerûn.

Description
Ascallion had a fearsome appearance, with prominent, sharp-edged, fang-like teeth. Adult female Ascallions could grow up to 18 feet long, while adult make Ascallions grew to about 8 feet in length. The female had a dark gray or black dorsal surface, and the male had a uniform color ranging from charcoal grey to black. Due to this coloring, male Ascallion were also called "Shadow". Young Ascallion were usually up to 1 foot in length and light grey in appearance.

Combat
Female Ascallion would hunt with their young. The young would be concealed in the mouth of the Ascallion, and upon sighting prey, the female would open her mouth so the young could attack. The female would let the young kill the prey, and consume the remains after the young had their fill. The female would only assist if the prey proved to be too much of a challenge for the young.

The jaws of the female Ascallion were incredibly powerful, with reports that they could easily pierce or splinter the hulls of small fishing boats. Unlike other ocean predators, Ascallion do not hunt by sensing vibrations in the water, relying only on their senses of sight and smell. This is a result of their centralized nervous system, which also limits the sense of touch and feel little to no pain. They are also immune to mental attacks and paralysis attacks.

Ecology
The Ascallion considers every lifeform in the water potential prey. Sharks are known to avoid areas occupied by Ascallion. Ascallion favor octupi above all other prey, and will even abandon a current attack if it senses an octupi near-by. Ascallion cannot live in fresh water for lengthy periods, and as a result Ascallion will swim into coastal rivers for brief periods of time. Ascallion spawn rarely, and the female will raise and protect the young. The young live in their mother's mouth until maturity, they then will attack and eat their way out of their mothers mouth. The young then disperse.

Reputation
Ascallion were feared and respected by aquatic and coastal communities, and a menace of fisherman.
