Acanthurus coeruleus is a surgeonfish found commonly in the Atlantic Ocean. Its length can reach 39 centimeters (15 inches). Common names include blue Atlantic pliers , blue barbers , blue doctors , blue fish , blue bar , surgeonfish blue pliers , yellow barber , and yellow doctorfish .

Distribution
Acanthurus coeruleus is common off the coast of Florida, the Bahamas, and other places in the Caribbean Sea, including Bonaire. Blue Tangs are very common in Belize and especially Ambergris Caye. They are also common in the Gulf of Mexico. They are also found in the south to Brazil and north to New York.

Description
Although coral fish bodies can vary in shade from light to dark blue, dorsal, anal and golden backs. As teenagers, the edges of the dorsal and rectal fins and rings around their eyes are purple-blue, blue or blue-green. Their colors change during the growth of the yellow, blue yellow subadult tail and the mature blue phase.
Acanthurus coeruleus shows biofluorescence, that is, when illuminated by blue or ultraviolet light, it radiates back as green, and appears different than under the illumination of white light (see picture on the right). Biofluorescence can assist in intraspecific communication and camouflage.
Ecology
Feed
Atlantic coral reefs inhabit coral reefs and grassy and rocky terrain on the coast, where there is a high prevalence of algae. They are herbivores, and their diet consists only of algae. They eat algae from the reefs where they are, as well as from the fish bodies around them. By eating algae from other fish, blue pliers serve as a cleanser for them. With the declining population of the antilumum diadema (sea urchin), the blue pellet population increases as the source of the algae used by the two animals is more.
The light blue fish eat continuously and eat a lot. This heavy eating need is due to the poor use of their food sources. The stomach and lining of the blue-breast intestine are adept at absorbing the crushed cellular content, but are not very effective at processing cellulose. The inefficiency of the digestive system causes blue stimuli to spend more time and resources in search of food in abundant and fast growing food sources at close range. It's close to abundant food sources allowing for continuous feeding.
Food competition
The distribution, density, and accessibility of food can determine population density and area size with blue stimuli. Areas with low biogenic structures are greater than higher biogenic structures. Since algae food sources are less dense in low biogenic structured areas, these areas should be larger to include the amount of food needed. This corresponds to the ideal free distribution model. This model states that competitors must adjust their distribution according to the quality of the habitat so that each individual will get the same amount of resources.
According to this model, there must be a lower tunge density in the lower biogenic structured region compared to the higher biogenic structured areas where there is a higher food abundance. In both areas, each individual will receive the same amount of resources due to competition. There was no significant difference in the rate of blue tanning feeding in each type of region, which meant that larger, uncolonized, and low density regions could match resources from them in smaller, higher density areas.
Cleaning behavior
Blue tass blue is involved in cleaning behavior with other fish as cleansers and clients. In this interaction, the cleanser removes parasites and other materials from the client surface. Clients benefit by having ectoparasites and damaged tissue removed from outside their bodies. Removal of unwanted organisms and tissues can lead to improved health maintenance.
Cleaner interactions
Atlantic blue teeth act as cleansers by grazing algae and eat the skin and parasites from client meat after clients come to the cleaning station. The most common client in this interaction is the green tortoise, where the blue pliers check the green turtle by biting the head, limbs, tail, and carapace.
Client interactions
When acting as a client, blue incentives are usually close to clearing stations inhabited by cleaner gobies. Blue tortoises are the most heavily examined area. Cleaners should be careful because the spine on both sides of the shaft is sharp and can cause painful wounds.
When in a client role, a blue stroke will appear as they enter the cleaning station. Posing occurs before the janitor checks the fish of the incoming client. Fish that pose while at a cleaning station have a higher chance of being cleaned. Blue tangs almost exclusively pose through the standing head.
Wound healing
Clients are cleaned with the benefits of blue pliers after injury. Blue tangs cause many minor injuries, but infection from injury rarely causes death. The recovery figures from minor and minor injuries are very high in blue. Infected blue tangsup is found to spend more time at the cleansing station as compared to further in the healing process. This shows that cleansing plays an important role in the wound healing process. Cleaners take wounds and eat dead tissue in the peripheral area.
Social mode
Blue tangs experience three different social modes: territorial, school, and wandering. Blue tung in non-territorial fashion forms school and wanders, while territorial blue tore is not. Territoriality reduces competition for food sources because one individual claims its territory and resources. In addition, schools allow fish to better overcome food defenses by others, and wandering allows for individual movements into dining areas, cleaning stations, and other resources. Social behavior is influenced by external conditions such as densityish density, similar population density, and life history stages.
Those who are in an aggressive and active territorial fashion pursue a disturbing blue throne. They swim more slowly and feed more often than non-territorial blue mites. School fishes form compact groups with other blue tangs in addition to other species. Territorial blue tongs are most commonly found in reef flat zones (sandy sand with rocks or corals) and are rarely found in spur zones (low-lying corals) or groove zones (sandy bottom ducts). The prevalence of territoriality decreases with increasing population of damselfish, and the time of day also does not affect the prevalence of territoriality.
Fish in school mode swim fast, eat moderately, and not aggressively, although they are often chased by damselfish. Schools are the most common in areas with high damselfish densities such as groove zones, spur zones, and top zones (shallow reef areas), while schools are most prevalent near midday.
often pursued by other fish. Wandering the blue tung also visit the cleaning station more often than there are in other modes. Wandering is most often found in the back zone of the reef (enclosed areas with irregular algae, rocks and sand) and during the morning. With similar population density increases, individual blue pliers become more territorial. Small, tung blue teens are territorial, but the occurrence of territoriality in the larger classes decreases. However, in these fish, schools and wanderings are on the rise.
Teen behavior
Teen blue teeth show different behaviors from both conditional and congeneric adults. Adolescents generally occur in the coral reef zones, spur zones, and on the fringe of the reef flat zone, but rarely within the reef flat zone. Teenagers stay solitary in their home ranges, and the region's size range increases with body size. This area overlaps with the one from [ Stegastes ] damselfish. Aggressive blue teeth are aggressive in territorial defense. They try to avoid stegastes , and are rarely pursued by this damselfish.
Relationships with humans
Though not under human threat, Atlantic blue pliers are captured for commercial fishing, but not so important to the Caribbean industry. It is also used, though rarely, as bait. This is also common in aquarium trade.
This fish has a low commercial value, gives a stinging smell. Ciguatera poisoning can occur if meat is consumed. The fish's tail spines are sharp, and only come out when the fish experience the excitement of some form. These fins can cut very deeply into human skin and have been known to cause infections, especially characterized by swelling and discoloration. The pain from such an infection can last for a long time, sometimes for hours. Some species of the genus Acanthurus are even considered to have poison glands in their tail spines.
