A fish decides where and how to move relative to its position in the school. Schooling fish watch one another and also feel the waves their neighbours make as they swim, with pressure-sensitive pores along their body called the lateral line. And each fish has its preferred spot in the school.
What are the benefits of schooling in fish?
Fish get many benefits from shoaling. These include defence against predators: if fish swim in schools, it is less likely any one of them will be eaten. Also, it may help a fish find food, and a mate. The school may even swim faster than a lone fish.
Do schools of fish make shapes?
The shape a shoal or school takes depends on the type of fish and what the fish are doing. Schools that are travelling can form long thin lines, or squares or ovals or amoeboid shapes. Fast moving schools usually form a wedge shape, while shoals that are feeding tend to become circular.
What are 3 types of fish?
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes).
How many is a school of fish?
There isn’t a magic number that defines a school. However, in the wild schools of fish are generally quite large, often numbering in the hundreds or even thousands. In captivity, schooling fish need to have at least four to six to create a comfortable school.
What are three reasons fish form schools?
Fish evolved to swim in schools to better protect themselves from predators, improve their foraging and swim more efficiently. Unlike shoaling, in which fish merely swim loosely together, schooling requires coordinated body positions and synchronized movement.
What is the behavior of a school of fish?
School. A school is a group of fish swimming in a synchronizing and polarized way. The individuals of this group adopt a schooling behavior (Pitcher, 1983). Schooling behaviors are characterized by the tendency to polarize, with individuals adopting the same orientation and swimming in the same direction.

Why do fish stay in school?
In biology, any group of fish that stay together for social reasons are shoaling (pronounced /ˈʃoʊlɪŋ/), and if the group is swimming in the same direction in a coordinated manner, they are schooling (pronounced /ˈskuːlɪŋ/).
What is the difference in a school of fish and a shoal of fish?
Here’s the difference: A shoal of fish swims together, but they are not swimming in unison or in any coordinated formation. In addition, any fish in the group may stop or break off at any time. A school of fish swims together as one fluid formation, with the movements of each fish an essential part of the whole.
What do fish swim in schools?
According to North Carolina Aquariums, fish swim in schools because schooling protects them from predators, encourages reproduction and makes it easier to find food. Schooling also conserves energy, as each fish drafts in the wake of the fish ahead of him. Schooling fish also rely on their lateral lines to detect vibrations from the fish around them.
