A group of fish is called a “school of fish.” It is a collective set of nouns that is most commonly used around the world to describe a group of fish swimming inside the water. Those of their own aquarium might observe this form of behaviour from the fish.
A collection of fish is also called a “shoal of fish.” The term “school of fish” was believed to be taken from the Dutch word “Schole.” There are several reasons why the fish swim in a synchronized manner in the water.
The primary reason is that they avoid larger predators by forming in the shape of a humongous fish. This creates a sense of fear in predators, who are usually much bigger than the lone fish.
They can camouflage and gel well with each other. Schooling or shoaling is possible only among fish because of their ability to adapt to each other. Besides, scientists have also found that they manage to do pretty well under any natural circumstance.
Additionally, fishes have enabled researchers to learn more about the behaviour of animals with higher vertebrates. For example, zebrafish are used for studying gene expression.

Origin of the Fish Group Name
What is called a group of fish? A group of fish is called a school or shoal of fish. This term was first used in Europe. They were taken from the Dutch word schole, which means a crowd or troop.
As we say, a crowd of people or a troop of soldiers. Likewise, a group of sharks forming a group in the ocean is known as a party. Please note that most marine animals roaming around in groups have their own specific names.
Forming a school or shoal helps in better bonding and communicating among the same category of fish. It is like an extended family that keeps roaming together. They are there for each other, and it becomes easier to avoid becoming prey for larger fish.
The average life of a fish depends on the type of fish, the nature where it lives, and the kind of food that it eats. Additionally, the climate where it resides will have a big say in it. Small and tiny fishes form shoals.
These fishes normally live for 10 to 20 years maximum. But some fish can live for more than 100 years.
Variations Based on Fish Species
According to research, there are more than 34000 species of fish around the world. They can be found in both salt and freshwater. These vertebrate animals come in different types ranging from ones with bones and some with no jaws.
They are able to swim together in tandem, beautifully synchronizing themselves without missing a single move. It is truly a marvellous sight. That is possible because of their streamlined body that is able to take shape and flow inside the water easily.
Besides, the fishes are similar in texture and pattern. They also match with their environment giving them a protective shell. It is possible to see different species of fish moving around together in a shoal or a school.
Fun Facts About Fish
1. Did you know that a school of fish can travel faster than a single fish?
As unbelievable as it sounds, a collection of fish is called a shoal can move faster than a single fish under the water. Their movements are extremely synchronized, and the sheer speed at which they move can be truly mind-boggling.
2. What are 3 types of fish?
There are primarily 3 types of fish found in the water. They are called the superclass or the Agnatha. These are the fishes that come without any jaws. The second type would be the class Chondrichthyes.
These fishes have cartilage in them. The third type of fish would be the superclass Osteichthyes. These fishes are mostly bony and come with several thorns in them. Most of the fishes are cold-blooded animals barring the warm-blooded opah species.
