Members of individualist or collectivist cultures may make different attributions of the origins and motivations of movement on a small scale among animated objects, or what would cause movement within a group of animated objects. Participants from the UK, China and Hong Kong were shown videos of animated fish on a computer screen. The videos depicted a central fish moving toward or away from a group of fish, and participants were asked to determine the relationship among the fish: internally motivated (the central fish was looking for food) or externally motivated (the central fish wanted to join the others). Another set of videos suggested that the group of fish was the predominant agent, with the individual fish being acted upon.

Neopterygii (from Greek νέος neos, new, and πτέρυξ pteryx, fin) is a subclass of ray-finned fish (Actinopterygii). Only a few changes occurred during the evolution of neopterygians from the earlier actinopterygians. They appeared sometime in the Late Permian, before the time of the dinosaurs. The neopterygians were a very successful group of fish, because they could move more rapidly than their ancestors.

The lower figure is a skeleton of the bowfin. The pelvic and pectoral girdles are both visible and the axial and cranial elements are also both present. The bowfin is an actinopterygii which means that the pectoral girdle is partly endochondral but mostly dermal bone. In this group of fish the fins function to maneuver, brake, and for slight positional adjustments.

An evolutionary timeline of the late Devonian vertebrate terrestrial invasion demonstrates the changes that took place. A group of fish from the Givetian stage began developing limbs, and eventually evolved into aquatic tetrapods in the Famennian stage. Pederpes, Westlothiana, Protogyrinus, and Crassigyrinus descended from these species into the carboniferous period and were the first land vertebrates. A particularly important transitional species is one known as Tiktaalik.

Asian carp, Shedd Aquarium, Chicago The group of fish species known in the United States as Asian carp include several which are invasive. These species of carp cause harm when they are introduced to new environments. Specifically, the four most well-known species of invasive Asian carp are bighead, silver, black, and grass carp. The black carp feeds on native mussels and snails, some of which can be already endangered.

Mud ring feeding (or mud plume fishing) is a cooperative feeding behavior seen in bottlenose dolphins on the lower Atlantic coast of Florida, United States. Dolphins use this hunting technique to forage and trap fish. A single dolphin will swim in a circle around a group of fish, swiftly moving his tail along the sand to create a plume. This creates a temporary net around the fish and they become disoriented.

Carp are a large group of fish originally found in Central Europe and Asia. Various carp species were originally domesticated in East Asia, where they were used as food fish. Carp are coldwater fish, and their ability to survive and adapt to many climates and water conditions allowed the domesticated species to be propagated to many new locations, including Japan. Natural color mutations of these carp would have occurred across all populations.

Most fish that are sold as tropical fish are freshwater species. Most species available are generally bred from fish farms in the far east and Florida where tropical temperatures make the commercial production more viable. Mass production of tropical fish from farms has led to many inexpensive fish available to aquarists. Tropical freshwater fish are the most popular group of fish because of the low price and ease of keeping in aquaria.

Since these fish live in a warm-water environment, they can reproduce all year long. Each group of fish consists of a breeding pair and none to four nonbreeders. Within each group there is a size-based hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning each fish is born male, but changes to female if the sole breeding female dies.

By their antennae, the bobbit worm senses the passing prey and snaps down on the prey to drag them into its burrow using its mouth. Some fish exhibit mobbing behavior to reduce predation risk, in which a group of fish will direct jets of water into the bobbit worm's burrow to disorient it. However, any quick strike by the mandibles of the worm can leave the fish stunned while also injecting a certain level of toxins.

The genus Dermocystidium was described in 1907. It was previously thought to be a genus of fungal parasites, related to the Thraustochytrida and Labyrinthulida (both those groups are now considered to be stramenopiles rather than fungi). Other biologists considered it to be a sporozoan protist. It was subsequently identified as one of a group of fish parasites (the "DRIP clade") of previously uncertain affiliation, which were later identified as nonanimal, nonfungal opisthokonts, and renamed as Ichthyosporea, and after expansion as Mesomycetozoa.

Since the Miocene era, species of Orestias have lived in relative isolation. Most of the aquatic regions in the Altiplano region are endorheic, meaning that they are closed off from drainage and do not let any water out. Thus, species of Orestias have been confined to their respective basins. Each group of fish is specifically adapted to the unique basin in which it lives and any alteration to the dynamics of the body of water would greatly impact the fish.

This is particularly true on the south side of the crescent-shaped Bunaken Island, lying in the heart of the park. A snorkeler or diver in the vicinity of Lekuan or Fukui may spot over 33 species of butterfly fish and numerous types of groupers, damsels, wrasses and gobies. The gobies, smallish fish with bulging eyes and modified fins that allow them to attach to hard surfaces, are the most diverse but least known group of fish in the park.

According to De Silva, there are 60 sharks species and 30 rays and skates found around the coast of Sri Lanka. Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. The following list of shark species recorded from the territorial waters of Sri Lanka.

Failing to find a description of the creature in any of her books, she attempted to contact her friend, Professor James Leonard Brierley Smith, but he was away for Christmas. Unable to preserve the fish, she reluctantly sent it to a taxidermist. When Smith returned, he immediately recognized it as a type of coelacanth, a group of fish previously known only from fossils. Smith named the new coelacanth Latimeria chalumnae in honor of Marjorie Courtenay-Latimer and the waters in which it was found.

Each spring, a multi-agency group of fish biologists use underwater lights to collect approximately 30,000 razorback sucker larvae along the shore of Lake Mohave, which would otherwise be eaten by introduced fishes. Larvae are then transported by boat to Willow Beach National Fish Hatchery where they grow in protected raceways for up to three years. When individuals have reached approximately 14 inches in length, they are released back into Lake Mohave in order to avoid predation by larger, introduced game fish such as striped bass.

Ovalentaria is a clade of ray-finned fishes within the Percomorpha, referred to as a subseries. It is made up of a group of fish families which are referred to in Fishes of the World's fifth edition as incertae sedis, as well as the orders Mugiliformes, Cichliformes, and Blenniiformes. It was named by W. L. Smith and T. J. Near in Wainwright et al. (2012) based on a molecular phylogeny, but the authors suggested that the group was united by the presence of demersal eggs that are attached to a substrate.

Fish social behaviour called ‘shoaling’ involves a group of fish swimming together. This behaviour is a defence mechanism in the sense that there is safety in large numbers, where chances of being eaten by predators are reduced. Shoaling also increases mating and foraging success. Schooling on the other hand, is a behaviour within the shoal where fish can be seen performing various manoeuvres in a synchronised manner. The parallel swimming is a form of ‘social copying’ where fish in the school replicate the direction and velocity of its neighbouring fishes.

Despite the fact that she is married to his uncle, Dorrigo felt the affair was justified because "the war pressed, the war deranged, the war undid, the war excused". In a metaphor for the novel's theme of fatalism, Amy observes while swimming a group of fish trying "to escape the breaking wave’s hold. And all the time the wave had them in its power and would take them where it would, and there was nothing that the glistening chain of fish could do to change their fate." After the end of the affair, he joins the Australian Imperial Force.

The island trevally is classified within the genus Carangoides, a group of fish commonly called jacks and trevallies. Carangoides falls into the jack and horse mackerel family Carangidae, the Carangidae are part of the order Carangiformes. The species was first scientifically described by the American ichthyologists Jordan and Gilbert in 1881 based on a specimen taken from the Revillagigedo Islands, which was designated to be the holotype. They named this new species Caranx orthogrammus, placing the species in a closely related genus of jacks, but this was later changed to Carangoides after further revision of the family had occurred.

In biology, any group of fish that stay together for social reasons are shoaling (pronounced ), and if the group is swimming in the same direction in a coordinated manner, they are schooling (pronounced ). In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives. Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate.

While areas accessible to salmon have been reduced over the past century through the construction of dams and the modification of river channels, this group of fish historically inhabited almost 13,000 miles of the Columbia River basin. Efforts from fishery management and state agencies, as well as the listing of several resident salmon stocks under the protection of the Endangered Species Act, has led to the re-establishment of accessibility to some parts of the Columbia River system for salmon. The regional return of salmon runs restores an important segment of local nutrient cycles, particularly that of nitrogen and phosphorus, to the system.

The subfamily Mormyrinae contains all but one of the genera of the African freshwater fish family Mormyridae in the order Osteoglossiformes. They are often called elephantfish due to a long protrusion below their mouths used to detect buried invertebrates that is suggestive of a tusk or trunk (some such as Marcusenius senegalensis gracilis are sometimes called Trunkfish though this term is usually associated with an unrelated group of fish). They can also be called tapirfish. Fish in this subfamily have a high brain to body mass ratio due to an expanded cerebellum (called a gigantocerebellum) used in their electroperception.

The whitefin trevally is classified within the genus Carangoides, a group of fish commonly known as jacks and trevallies. Carangoides falls into the jack and horse mackerel family Carangidae, the Carangidae are part of the order Carangiformes. The species was first scientifically described by Dutch naturalists Coenraad Jacob Temminck and Hermann Schlegel in 1844 based on a specimen taken from the waters off Japan, which was designated to be the holotype. They named the species Caranx equula, although the species was later moved to Carangoides, as well as having a new genus created for it, Kaiwarinus.

Clean, fast-flowing streams and rivers are required for the freshwater pearl mussel, where it lives buried or partly buried in fine gravel and coarse sand, generally in water at depths between 0.5 and 2 metres, but sometimes at greater depths. Clean gravel and sand is essential, particularly for juvenile freshwater pearl mussels, for if the stream or river bottom becomes clogged with silt, they cannot obtain oxygen and will die. Also essential is the presence of a healthy population of salmonids, a group of fish including salmon and trout, on which the freshwater pearl mussel relies for part of its life cycle.

The barcheek trevally is classified within the genus Carangoides, a group of fish commonly called jacks and trevallies. Carangoides falls into the jack and horse mackerel family Carangidae, the Carangidae are part of the order Carangiformes. The species was first scientifically described by the Dutch ichthyologist Pieter Bleeker in 1857 based on a specimen taken from Ambon Island in Indonesia, which was designated to be the holotype. Bleeker named this new species Carangoides plagiotaenia, placing the species in what is still considered to be the correct genus, while later revisions transferred it to the genus Caranx which was later considered to be an invalid move.

A group of fish in a posh restaurant's tank swim together casually, until they look at the customers outside of the tank and see their friend Howard being eaten. This leads them to question the meaning of life. The question is explored in the first sketch, "The Miracle of Birth", which features a woman in labour being ignored by the doctors in favour of impressing the hospital's medically-clueless administrator. Meanwhile, in Yorkshire, described as "the third world", a Roman Catholic man loses his job and returns home to tell his numerous children that he will have to sell them off for scientific experiments due to the Catholic church's opposition to contraception; this leads to the musical number "Every Sperm Is Sacred".

The CWT is not visible once inside the fish; its presence is detected at close range by using a handheld wand or tunnel type detector that can sense the magnetized metal. A number code unique to either a group of fish or an individual fish is etched into the surface of the CWT, and to read the code the fish is killed first so that the tag can be removed and inspected under a microscope. Upon insertion, information about the fish such as hatching date, release date, location, species, sex, and length are recorded along with the corresponding tag code into a database, so that codes on recovered tags can be matched to information within that database. Coded wire tags have been used to research fish species from over 40 different families.

2 villains and 2 bordars and of meadow. In the Middle Ages, Everdon Priory was a small Benedictine priory, located at the eastern end of the village, close to a group of fish pools, which are still extant. It was a daughter house of the abbey of Bernay, in Normandy, and was granted lordship of the manor of Everdon. Like most alien priories, it was dissolved in 1415 under an Act of Henry V. In 1440 Henry VI granted the property of the priory to the newly founded Eton College, which established a manor house on the site.Victoria County History: Northamptonshire, volume 2, chapter 46: the Priory of Everdon A junior branch of the Spencer family from Badby took up the lease of the Eton College Manor house around 1500.

One of the aims of the EU-funded Horizon 2020 Project ParaFishControl, was to establish the first in vivo and in vitro culture system for myxozoan proliferative stages (based on S. molnari blood stages), excluding full life cycle production. Such a system allows for the production of large numbers of host-free parasite stages for genomic/transcriptomic analyses, analyses on host-parasite interactions, and the establishment of test systems for antiparasitic/immunostimulatory substances, molecular interference approaches or vaccine trial. An experimental research model for proliferative stages is urgently required for myxozoans, for which no treatments are available but which appear to be an important group of fish parasites on the rise. First transcriptomic datasets of blood stages have been studied with regard to its arsenal of proteolytic enzymes,Hartigan A, Kosakyan A, Pecková H, Eszterbauer E, Holzer AS (2020) Transcriptome of Sphaerospora molnari(Cnidaria, Myxosporea) blood stages provides proteolytic arsenal as potential therapeutic targets against sphaerosporosis in common carp.
