FISH.
From Wikipedia, the free encyclopaedia
A fish is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and
equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with
species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean
(e.g., gulpers and anglerfish). Fish are of tremendous importance as food for people around the world, either
collected from the wild (see fishing) or farmed in much the same way as cattle or chickens (see aquaculture). Fish
are also exploited for recreation, through angling and fish keeping, and are commonly exhibited in public aquaria.
Fish have an important role in many cultures through the ages, ranging as widely as deities and religious symbols to
subjects of books and popular movies in various cultures.
