Definition of school of fish

The concept of Bank Of fishes designates the set of simile fish that do not necessarily have to be the same species, such is the case of tuna and sardines, to name a few, and which are characterized by swimming in a synchronized and concentrated way. Popularly it is common for the concept to appear designated as shoal.

The most notable feature of a school of fish is the similarity of those who compose it. Fish make use of many tricks to align themselves with those "companions" that are similar in size, in species, in Health, origin and affinity. Is tactic moving together with their almost equal pairs has a special effect that in the case of running into predator no member of the bank is appreciated with predilection over the rest, that is, the mentioned technique it facilitates homogenization and therefore the "distraction of the predator on duty".

Now, it is worth mentioning that this ability to associate with other similar fish is not a skill with which the fish is born, but is going to learn it, an explanation of this is found in that the fish cannot

perceive his own color, then, tends to be associated with those that he perceives as similar and with those that at some point he was successfully integrated.

It should be noted that mobilization in this way provides numerous advantages to the animals that do so, in this particular case, to the fish, it helps them to protect itself from predatory species, perfects its own predation, increases its hydrodynamic efficiency and facilitates the encounter with companions, among the most featured.

Among the most common movements made by schools of fish are the migratory , which consist of the displacement from one place of origin to another of destination and that will involve a change in the habitat habitual. These can be periodic, seasonal or permanent in time.
