Scarus coelestinus és una espècie de peix de la família dels escàrids i de l'ordre dels perciformes.
Der Mitternachts-Papageifisch (Scarus coelestinus) ist eine Art der Papageienfische, die im tropischen Westatlantik von den Bermudas und der Küste des südlichen Floridas über die Karibik bis an die Küste des südöstlichen Brasilien vorkommt.
Die Art wird etwa einen halben Meter lang, kann aber auch wesentlich größer werden. Dokumentiert sind Längen bis zu 77 cm und ein Gewicht von 7 kg. Der Mitternachts-Papageifisch ist schwärzlich bis dunkelblau gefärbt. Die Mitte zahlreicher Schuppen und die schuppenlosen Bereiche am Kopf sind hellblau, wie auch ein schmales Band zwischen den Augen. Die Zähne sind grün-blau. Der Mitternachts-Papageifisch ist der einzige so gefärbte Papageifischart im tropischen Westatlantik und somit unverwechselbar. Ein Geschlechtsdimorphismus besteht nicht und auch Jungfische und adulte Fische sind sehr ähnlich gefärbt.
Mitternachts-Papageifische leben gewöhnlich in Tiefen von 5 bis 20 Metern, seltener auch bis in Tiefen von bis zu 75 Metern. Sie ernähren sich vor allem von Algen und sonstigem Aufwuchs, den sie von Felsen und Steinkorallen abschaben. Die Art bildet kleine Schwärme, oft zusammen mit Doktorfischen.

The midnight parrotfish (Scarus coelestinus) is a species of parrotfish that inhabits coral reefs mainly in the Caribbean, Bahamas, and Florida.
The typical size is between 30 and 60 cm, but it can grow to almost 1 m. It has been observed as far north as Maryland and as far south as Brazil.[3] Usually found between 3 and 80 m deep, it swims over reefs and sandy areas, where it feeds on algae by scraping it with its teeth fused into a beak.
The midnight parrotfish has a deep blue body with light blue patches along its sides and head. The exact location of light blue patches differs between each fish, but all midnight parrotfish have a light blue patch on the underside of the beak.[4] Unlike other parrotfish species, the midnight parrotfish retains its coloring through its juvenile and adult stages of life. Both male and female midnight parrotfish exhibit this coloring.[5] The parrotfish gains its name from its hard beak it uses to scrape its food from hard substrates.[6]
The midnight parrotfish, along with other parrotfishes, is primarily a herbivore. Their main source of food is algae, which they scrape from coral and other hard substrates using their beak. Through this process, the parrotfish also consumes carbonate sediments and assists in moving sediment around the reef. The midnight parrotfish can take up to 16,000 bites a day as an adult, and 28,000 a day as a juvenile.[6] In addition to herbivory, evidence suggests that midnight parrotfish also consume sergeant major damselfish eggs.[7] Unlike other species of parrotfish that live in mangrove forests, the midnight parrotfish has not been shown to consume sponges.[6]
The midnight parrotfish inhabits coral reefs mainly in the Caribbean, southern Florida, and the southern Gulf of Mexico, but has been found as far north as Maryland and as far south as Brazil.[8] Midnight parrotfish were found to be the only species of 32 Caribbean reef fishes to not have a significant zonation among patch or crest reefs. While less abundant than other parrotfish species such as the queen parrotfish (Scarus vetula), striped parrotfish (Scarus iseri), stoplight parrotfish (Sparisoma viride), and redband parrotfish (Sparisoma aurofrenatum), the midnight parrotfish is an important part of the trophic web. Like other parrotfish, the midnight parrotfish controls algal populations through feeding, and encourages coral growth through its grazing.[5] Midnight parrotfish have been found at depths between 5 and 75 meters.[9]
Midnight parrotfish typically do not exhibit schooling behavior, as they are able to feed on algae without the assist of other organisms. Midnight parrotfish have been seen to school with up to 30 other individuals in order to secure food from damselfish nests. Typically heavily guarded by the damselfish, schools of midnight parrotfish can overwhelm a nest and secure both the algae within it and the eggs of sergeant major damselfish. Bite scars within the sergeant major damselfish nests indicate this behavior is common. As with other large species of parrotfish, the midnight parrotfish typically occurs in lower concentrations throughout most of its habitats. Higher concentrations of parrotfish are more common in areas with low fishing.[7]
Midnight parrotfish are also known to exhibit co-schooling behavior with blue tang. The arrangement allows both species to feed on algae, and provides the parrotfish with protection. The coloring of blue tang schools camouflages the parrotfish, as its dark blue pigment matches that of the blue tang while its light blue pigment matches the rays of sunlight between blue tang. Blue tang have ventral spikes, which has the added benefit to the parrotfish of wielding away predators. The schools are typically composed of 50 to 400 blue tang with up to 17 midnight parrotfish, although a majority of schools include 1 or 2 parrotfish. Both blue tang and parrotfish compete with damselfish for algae, and the co-schooling behavior allows both species to gain access to damselfish-protected algal clumps.[4]
Midnight parrotfish are cited as 'Least Concern' on the IUCN Red List. This is due to the high concentrations of midnight parrotfish in the Gulf of Mexico and Caribbean. Midnight parrotfish are protected species in United States waters, as well as a number of marine protected areas in the Caribbean. However, Cuban spear-fishers often target the midnight parrotfish along with other parrotfish species, which has led to a slight decline in population.[9]

Se encuentra desde Bermuda, las Bahamas y Florida hasta Río de Janeiro (Brasil).
Scarus coelestinus, communément appelé Zawag bleu, est une espèce de poisson-perroquets qui habite les récifs coralliens essentiellement dans les Caraïbes, les Bahamas et sur les côtes de Floride.
Il mesure généralement entre 30 et 60 cm, mais peut atteindre près de 1 m. Son aire de répartition s'étend du Maryland, au nord, jusqu'au Brésil, au sud. Habituellement, on le trouve entre 3 et 80 mètres de profondeur, il nage dans les récifs et sur les bancs de sable où il se nourrit d'algues en les broutant avec ses dents fusionnées en un bec.

Scarus coelestinus (Valenciennes, 1840), noto comunemente come pesce pappagallo blu[2] è un pesce osseo marino appartenente alla famiglia Scaridae.
Endemico dell'oceano Atlantico occidentale tropicale nel mar dei Caraibi e dalle Bermuda, Bahamas e Florida meridionale fino al sud del Brasile. Vive su fondi duri, scogliosi e corallini a profondità tra 5 e 75 metri (di solito non oltre 20 metri)[3].
L'aspetto è quello tipico dei pesci pappagallo con corpo ovale fusiforme e denti fusi in un becco. Il becco ha color verdastro o azzurrognolo. Il colore del corpo è scuro, da indaco a nerastro con il centro di alcune scaglie e parti del muso blu brillante. Una fascia blu è anche presente sugli occhi. La taglia massima nota è di 77 cm, la media è di 50 cm. Il peso massimo registrato è di 7 kg[3][4].
Di solito si trova in banchi, spesso assieme a pesci chirurgo[3].
Si nutre di alghe che gratta da scogli e corallo[3].
Questa specie viene catturata per il consumo umano laddove è comune[3]. Non esiste comunque una pesca specifica a questa specie[1].
Viene allevato negli acquari marini anche se da adulto raggiunge taglie notevoli per cui può essere ospitato solo da acquari pubblici[3].
Lo status delle popolazioni non è noto con certezza. Esistono comunque evidenze che in alcune aree le popolazioni si stiano riducendo a causa della sovrapesca[1].
