Before proceeding to determine the meaning of the term shoal, it is necessary to establish what its etymological origin is. In this case, it must be stated that it is a word of Galician-Portuguese origin, as it derives from “shoal”, which is used to refer to a group of fish.
That word that is the result of the sum of two clearly delimited parts:
-The noun “card”, which refers to a brush with barbed wires that can be similar to a group of fish.
-The suffix “-ume”.

It can be said a school is a school of fish. However, the notion of bank often used to mention a set of fish belonging to the same species and swimming synchronously. The schools, on the other hand, can be made up of fish of different species.
The formation of schools obeys various biological criteria. When fish move together, they improve their defense against potential predators and, in turn, increase their own chances of obtaining food. As a school forms, the fish can also find mates more easily.
The fact that the fish swim in synch and move together makes the school a kind of unit. That is to say: beyond being made up of hundreds or thousands of individual specimens, the school seems to act as a single organism.
One of the most curious facts about the school is that it is considered that the fish by moving in this way save energy and effort. In particular, each fish, by taking advantage of the waves caused by the one in front of it due to its movement, will have to make less effort. Exactly the studies carried out in this regard indicate that it allows each individual to save up to 65% of energy.
It should be noted that, in some countries, a shoal is called an accumulation or agglomeration of elements, according to what is stated by the DigoPaul in its dictionary: “A shoal of technology companies settled in the city thanks to the tax benefits “, ” The festival will feature a school of international stars. “
