Hello guys, today we gonna explain and answer the question about : is a fish an animal and tell you many interesting and important informations about fishs. So be here, keep reading and discovered the world.
Is a fish an animal
Fish are animals that have colonized almost all aquatic ecosystems : oceans to extreme depths (soles have been seen in the Mariana Trench, at more than 10,000 m deep), lakes and rivers sometimes at very high altitudes and in areas with very different temperatures.
The fish are provided with gills , which allow aquatic respiration, and fins, the number and shape of which differ according to the groups.

Are fishs considered as animals
▪️Fish is one of the five basic categories of vertebrate animals, while the other four are mammals, reptiles , amphibians , and birds , and fish have fins that help them swim and gills enable them to breathe oxygen underwater, and fish consists of more than 30,000 species, where the number of fish species exceeds the types All other groups combined.
▪️Fish vary a lot in shape, color, and size of all kinds, as they may be in the form of worms with twisted bodies, or be flat so that they are almost flat, or look like a rock, and the smallest size does not exceed a centimeter and a half in length, and the largest of them is the whale shark, which is more than two Ten meters.
▪️These fish live in all water bodies on Earth, in very cold waters in the Arctic, and they live in tropical waters that are almost boiling point, and in mountain rivers and streams that flow under the surface of the earth, and some of their species live most of their lives buried in mud or bottom sand The sea, and fish are of great importance to humans, so fishing is a source of livelihood and food for many people, and some may hunt them for sport and entertainment, while many pet lovers keep them as decorative fish, and some of them may be harmful to humans, as sharks, piranha and barracuda attack humans in some cases And the bites of some poisonous fish cause death.
Is a fish an animal yes or no?
Fish are one of the animals that live in the water, because they have gills that help them in the process of breathing oxygen under the water, and the most important characteristic of fish is the large number of types, as it is divided into more than thirty thousand species, according to their shape, size, color and other different characteristics.
Do Fish Count As Animals?
Of course, and they are distinguished as vertebrate animals, that is, those that have a backbone that supports their body, as well as contain bones or cartilages, and this difference is the essential difference between them and many marine animals, the fact that most of these animals do not have a backbone, such as crabs, prawns, mollusks and squid, which all belong to crustaceans.
Is a shark an animal yes or no?
We answered before that is a fish an animal, know let's move a little to sharks.
▪️The shark is an animal, and specifically a cartilaginous fish of a class, and the order of Echinacea or Selachii, and there are more than 400 species of it alive, which are classified into 14-30 families according to different classifications. The shark is often hunted for commercial purposes, and overfishing at the end of the twentieth century and the beginning of the twenty-first century led to a decline in the numbers of some species.
Some informations about sharks
Diet
▪️Most species of sharks feed on fish, crustaceans, mollusks, plankton, krill, marine mammals, and other sharks, and they have a strong sense of smell that allows them to pick up the smell of blood in the water many miles away.
The senses
▪️Has the thickness of the shark six senses used for fishing, and communicate with each other , these senses are: sight, hearing, smell, taste, and touch, electric and reception can shark detect the small electric field produced by the animals when they constrict his muscles, and is similar to the installation of the eye shark with Human eye; The pupil expands in many types in response to different levels of light, and the eye is made up of a cornea, lens, pupil, iris, and sticks, and many types include cones.
Breathing
▪️The shark has a row of gill slits , and it differs from bony fish in that it has five slits on both sides of its body, and some species may have six or seven of them, while bony fish have only one slit.
Places to live
▪️Sharks can be found in all salt water bodies in the world, and they are more common in warm waters, and sharks can live in wide water habitats and at different temperatures; Where some species live in shallow coastal areas, while others live in the deep waters of the ocean floor, and in the open ocean.
What type of animal is a fish?
Fish are among the oldest living things on Earth. They lived on Earth before dinosaurs, nearly 500 million years ago, fish are vertebrates, as they have a backbone.
The number of fish known so far reaches more than 25 thousand species, they not have lungs, but they breathe through gills, where they absorb oxygen and send it to the parts of their body.
Fish properties
Not all animals that inhabit the seas are fish, as they belong to many groups, and one of the main differences between fish and many other water creatures is that they have a backbone and bones (or cartilages) that support their body, but many marine animals are boneless invertebrates, among them Crustaceans, such as crabs and prawns, or mollusks, such as octopus and squid, or many other creatures, including worms, jellyfish, and sponges.
There are some marine vertebrates that are not fish either, as many people think because of the similarity in shape that whales and dolphins are fish, but these animals are considered mammals, because they lack gills.They need to breathe oxygen from the open air, and then hold their breath for as long as they are underwater for a period that may exceed an hour, and whales are warm-blooded while fish are cold-blooded (they cannot regulate their body temperature internally).

Types of fish
▪️Fish are vertebrate animals, and they are divided into two main categories according to the classification of biologists, which are bony and cartilaginous fish, and most fish are considered bony, with a number of approximately 24,000 species.
▪️The main difference between the two groups is that the fish bone whole structure of the bones supporting her body, and protects functional members, they also have special members to help them float in the water all the time, and most of the fish species represent, and the cartilaginous, the most important fish sharks of all kinds and rays They only have soft cartilage in their bodies, and they cannot stay afloat unless they continue swimming permanently.
▪️Cartilaginous fish are also distinguished by the advantage that when they reproduce, they fertilize their eggs internally, and then lay a small number of large-sized eggs, and they are rich in salt on which young embryos feed, and some even give birth to their young alive after hatching inside them, and as for bony fish, the males fertilize eggs after they emerge from The female body, and her eggs are very small (they may not exceed a millimeter in diameter), while their number is very large, and they do not provide much parental care for their young.
Biological features of fish
One of the most important features of fish is that they are able to absorb oxygen from the water with their gills, and they absorb oxygen, and then release carbon dioxide into the water, and in order for fish to breathe, they must enter and remove water from their gills by moving the jaw, and for this the fish are seen closing and opening their mouths On the other hand, on the other hand, these animals are not able to breathe oxygen from the open air, and therefore they (with few exceptions) are unable to live outside the water, and fish have special organs that regulate salinity in their body, as the kidneys and gills are adapted to filter or retain salt according to their habitat. If it was in the ocean or fresh lakes and rivers.
The senses of fish differ according to their needs. If they live close to the surface of the water, they have small eyes, and if they inhabit the depths, their eyes become large in size to help them capture the fading light in the depths, and in most types of fish there is one eye on each side of its head, so that You can see most of their surroundings, and some fish have a very strong sense of smell, so sharks can smell blood in the sea very quickly to chase their victims, and these organisms have no external ears, and they are unable to make sounds except by moving their body muscles.
The nutritional value of fish
▪️Fish extracted from the sea is an important food that a person depends on, because of its great benefits and many elements that the body needs, and because it is available to many residents of poor countries who may not be able to buy meat at high prices, and fish may spoil quickly if not preserved. Many of them lose their validity within twelve hours of hunting in the tropical heat, and therefore it is imperative to preserve them (by salting, smoking, drying or fermentation) to deliver them to the largest number of people, and the meat of these organisms is an excellent source of high-quality proteins, as it contains High amounts of some minerals, such as calcium, iron, and vitamins such as vitamin A and others.
▪️Fish meat is classified into categories according to its nutritional value, white fish is almost free of fat (about 1%), and oily fish - including sardines - may contain 25% of fat, but it is rich in vitamins and fatty acids that are beneficial to humans because of their solubility In fat.
Fishing
The process of fishing, whether in fresh or salt water, is done through the use of a hook, line, and hook, and fishing is similar to fishing, as it originated as a means of obtaining food for survival, and the origins of fishing date back to about 2000 BC to the ancient Egyptians, and the concept of fishing appears. Since the fourth century BC through Chinese references, which show the use of a thin thread of silk with a hook made of a needle and a rod of bamboo.

Fishing methods
-Bait fishing
The method of fishing using bait is one of the oldest and most used methods around the world, and this method is used to catch coarse fish, such as seabream, barb, tuck, etc., where the bait is hung on the hook, which the fisherman sets so that the head of the penis is raised in the event that it is swallowed by the fish. On common baits: worms, small fish, bread paste, cheese, and small bits of vegetables and grains, then the fisherman grabs the penis and throws it into the water, waiting until the fish are swallowed up.
Fishing with artificial flies
▪️Fly-fishing, and fishing is done in this way through the use of a rod ranging in length between 2.1-3.4 meters, a light reel, and a heavy line and coated with plastic and linked to a head lighter than nylon, the rod is used to catch artificial flies, Made of hair, feathers, or synthetic materials to mimic the natural food sources of fish, and then this artificial fly bites the long strings of the rod back and forth, and this bait must be lowered quietly on the surface of the water, and an example of fish that is caught in this way is salmon Trout and regular salmon.
Networks
▪️There are a variety of nets that are used for fishing, which is considered a good way to fish, and examples of these nets in the past are the trawl nets, which are pulled and pulled using a boat, as these nets reach a limited depth and are not specific to the type of fish when fishing, and then it is The development of these nets to be used in fishing, as they reached a depth of 2500 meters, and included devices that work to exclude mammals and turtles.
Fisheries
▪️In the past, fisheries were used to catch a large number of fish, as this trap is placed in the water, with a fence made of weeds and sticks, leaving an opening that resembles a fish's mouth, and this mouth attracts live fish, and sends it towards the hook, and the mouth of this trap encourages the entry of fish to Trap and prevent them from leaving again, as this trap is designed to catch large fish, not small fish, as they can leak from between its folds.
