	Fish - Wikipedia, the free encyclopedia
		A fish is a poikilothermic (cold-blooded)* water-dwelling vertebrate with gills.
		Taxonomically, fish are a paraphyletic group whose exact relationships are much debated; a common division is into the jawless fish (class Agnatha, 75 species including lampreys and hagfish), the cartilaginous fish (class Chondrichthyes, 800 species including sharks and rays), with the remainder classed as bony fish (class Osteichthyes).
		Endothermic teleosts (bony fishes) are all in the suborder Scombroidei and include the billfishes, tunas, and one species of "primitive" mackerel (Gasterochisma melampus).

	FISH, a quick course on Ichthyology
		Fish evolved in fresh water; the chondrichthyes moved to the sea early in evolution, while the bony fishes went through most of their evolution in fresh water and spread to the seas at a much later period.
		Fish are the dominant free swimming animals of the seas.
		Fish come in all shapes and sizes, some are free swimming, while others rest on the bottom of the sea, some are herbivores and others are carnivores, and some lay eggs while others give live birth and parental care to their young.

	Fish Textbook
		Lampreys, cartilaginous fishes, and a few bony fishes have a flap of tissue that spirals around the inside of part of the intestine, thus increasing the surface area for nutrient absorption.
		Unlike typical fishes, fishes that use the swim bladder as a lung have a tube that connects the swim bladder to the mouth.
		In most bony fishes, the dorsal fin is used for sudden direction changes and acts as a "keel" to keep the fish stable in the water.

	All About Fish
		The gills of a healthy fish are bright red due to the high level of oxygen in the blood that is very close to the surface of the gills.
		Fish with fusiform, or streamlined, bodies are usually fast swimming predators that may swim at high speeds much of the time or are capable of great bursts of speed.
		In most bony fishes, the dorsal fin is used for sudden direction changes and acts as a "keel" to keep the fish stable in the water.

	ADW: Actinopterygii: Information
		Fish development is known for its confounding terminology, so there are many gray areas within these major categories, and, as with many other animals, many species tend to defy classification into discrete categories.
		Nearly all bony coral reef fishes produce pelagic young (meaning they live in the water column for a period of time before settling on reefs), and the length of the stage is highly variable, from only a week in some damselfishes to greater than 64 weeks in some porcupine fishes.
		Pheromones allow fish to recognize specific habitats (such as natal streams in salmon), members of the same species, members of the opposite sex, individuals in a group or hierarchy, young, predators, etc. Some groups in dominance hierarchies even associate the scents of individuals with their particular ranking.
