Languages have always been my passion and I have studied Linguistics, Computational Linguistics and Sinology at the University of Zurich. Another example is that there are several different collective nouns to refer to ants including swarm, army, column and state. [30] The LLO is essential in the final stages of a predator attack. Synonyms for group of fish include school of fish, shoal, aggregation of fish, school, shoalmate and pod. It has been shown that small fish avoid joining a group with larger fish, although big fish do not avoid joining small conspecifics. This ability was demonstrated by Pitcher and others in their study of foraging behaviour in shoaling cyprinids. They aggregate together in huge numbers. [7] Because of their adaptation to schooling behaviour they are rarely displayed in aquaria. A simple group of fish is called a "shoal." You can use cluster, swarm, drift, hive, or erst to describe a group of bees. [1][a] Although shoaling fish can relate to each other in a loose way, with each fish swimming and foraging somewhat independently, they are nonetheless aware of the other members of the group as shown by the way they adjust behaviour such as swimming, so as to remain close to the other fish in the group. Working together in larger numbers also makes it possible for fish to find mates. Landa (1998) argues that the leader of a school constantly changes, because while being in the body of a school gives a hydrodynamic advantage, the leader will be the first to the food.[13]. var _g1; It is commonly observed that schooling fish are particularly in danger of being eaten if they are separated from the school. Large numbers also help fish find mates.
[51] Lunge feeding is an extreme feeding method, in which the whale accelerates from below a bait ball to a high velocity and then opens its mouth to a large gape angle. Fish aggregations can be structured or unstructured. Most forage fish are pelagic fish, which means they form their schools in open water, and not on or near the bottom (demersal fish). The senorita fish pick dead tissues and external parasites, like parasitic copecods and isocods, from the skin of other fishes. Corralling is a method where fish are chased to shallow water where they are more easily captured. During the day the Humboldt squid behave similar to mesopelagic fish, living at depths of 200 to 700 m (660 to 2,300 ft). For the alternative rock band, see, Many eyes provide a higher level of vigilance, ↑ Diagram illustrating the difference between, ↑ Large schools, like this one, still follow positional evaluation and are regulated by the same density and volume characteristics as smaller schools, Other collective nouns used for fish include a, Shoaling is a special case of aggregating, and schooling is a special case of shoaling. [32] In filter-feeding ancestors, before vision and the octavolateralis system (OLS) had developed, the risk of predation would have been limited and mainly due to invertebrate predators. They have a symbiotic relationship with the parasite eating senorita fish. They provide increased access to potential mates, since finding a mate in a shoal does not take much energy.

Larger capelin also eat krill and other crustaceans. If you happen to spy a group of fish that is swimming sort of casually while looking for food and you happen to notice that there are a couple of different species making up the group then you will probably best benefit from calling the group a shoal of fish.
