Schooling also has disadvantages, such as excretion buildup in the breathing media and oxygen and food depletion. The way the fish array in the school probably gives energy saving advantages, though this is controversial. [5] Schools of forage fish often accompany large predator fish. Here a school of jacks accompany a great barracuda.
A bait ball, or baitball, occurs when small fish swarm in a tightly packed spherical formation about a common centre. [1] It is a last-ditch defensive measure adopted by small schooling fish when they are threatened by predators. Small schooling fish are eaten by many types of predators, and for this reason they are called bait fish or forage fish.

There are plenty of fish in the sea, but there's only one robotic school. Harvard researchers created a robotic school of fish that can coordinate their movements without any kind of controls from ...
Radakov estimated herring schools in the North Atlantic can occupy up to 4.8 cubic kilometres (1.2 cu mi) with fish densities between 0.5 and 1.0 fish/cubic metre, totalling several billion fish in one school. [111
A couple of divers in South Africa are encircled by a large school of fish while exploring a shipwreck off the coast of Umkomaas.
When the phytoplankton die, they may create dead zones, so-called because they are hypoxic (low in oxygen). This in turn kills fish and other animals, but not jellyfish, [94] allowing them to bloom. [95] [96] Jellyfish populations may be expanding globally as a result of land runoff and overfishing of their natural predators.
Zangroniz said studies only use a few species of fish and don't represent the more than 30,000 fish species that exist. She added pain is measured in mammals on the grimace scale, often seen in ...
