Fish
|
Fish are gill-bearing animals that lack limbs with digits, they're aquatic animals, meaning they only live in bodies of water. Much like squid, they are found in almost any water source, including lakes, oceans, puddles, seas, rivers, creeks, swimming pools and ponds. Fish have always been a popular food source among all races, especially Humans and Kharajyr. Fishing as an occupation or for leisure is very common among the Halflings.
Fish can be eaten raw but is almost always cooked. It can be added to other dishes such as stews. In Anthos, the number and variety of fish are thought to be much higher than in any other realm.
Appearance
The skin of most fishes is covered with scales, which, in many cases, are animal reflectors or produce animal coloration. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes.
Furthermore, most fish exchange gases using gills on either side of the head. Gills consist of threadlike structures called filaments. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. The gills push the oxygen-poor water out through openings in the sides of the head. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gill opening on each side. This opening is hidden beneath a protective bony cover called an operculum.
The size of a fish can vary greatly, depending on the type of fish. With fish like whale sharks being enormous fish of up to 12.65 meter (41.5 ft) long, but fish like the dwarf pygmy goby only being 9 millimeter (0.35 in) long. It's shape and other distinctive features also depend on what species you're dealing with, though all fish have gills and digitless limbs known as fins, if they even have any limbs.
