Parrot fish psittacosis fish
(Scientific name: Scaridae)
A species of nearly 80 species of fish that live on coral reefs in warm and semi-warm seas, and took its name from its two unusual front teeth that resembles a parrot's beak.
Smit this fish by this name because of its front row teeth in the introduction of the mouth similarly to parrot beak, fish lives freely in the warm waters between the coral reefs in the oceans and seas, and it There are about eighty to a kind of dimension Between 20 cm (small) to a meter and a half (giant).
Size Variable fish psittacosis between 10 cm and over 1.2 m. There are about eighty-one. It is that objects of thickness covered by considerable crusts. Most fish psittacosis brilliant colors, even for the most part during his life...
Eating fish often psittacosis algae recused from rocks and reefs with solid teeth. And it feeds on many fish psittacosis of the marine grasses that exists on the coral reefs and often considers in big banks. And a psittacosis fish of the queen who lives in the warm regions of the Atlantic Ocean to swim, sometimes in groups consisting of three or four male and female fish.
And at night there will be a transparent slave cover that looks like a cocoon takes itself and is even where shines the light of day and the predator index at night. After ingestion of food come out in the form of sand, each fish is able to produce 90 kg of sand per year.
Although they are considered herbivores, parrotfish eat a wide variety of reef organisms, and they are not necessarily vegetarian. Species such as the humpback parrot (Bolbometopon muricatum) integrate coral (polyps) into their diets8. The teeth grow continuously, to compensate for wear due to feeding9. The pharyngeal teeth crush the coral and release the coral algae10 that the fish will assimilate via its long intestine. Ingested limestone is subsequently released as a sediment cloud7.
Within the family, there are two types according to their mode of feeding: the "shredders" (excavators) and the "scrapers" 11. The first (all Chlorurus, as well as Bolbometopon, Cetoscarus and Sparisoma viride) are provided with a particularly powerful beak, and leave deep traces in the coral. The latter merely scratch the superficial algal film. Only the powerful Bolbometopon muricatum feeds mainly on coral11, the others having a more diversified diet consisting of marine grasses and algae, such as those of the genus Halimeda.
Parrotfish are distributed throughout the world mainly in tropical areas but also for certain species in subtropical zones. The region where the concentration and variety of species is the most important is the Indo-West Pacific3. However, species of the genus Sparisoma are found in the tropical Atlantic Ocean (as well as the species Nicholsina ustus), and the species Sparisoma cretense is found as far as the Mediterranean Sea.
The preferred environment for parrotfish varies with species and consists of coral lagoons, reef flats, reef slopes, outer reefs, zosteraceae grasslands and rocky areas between 1 and 30 m deep. Their abundance is maximum in the zone of 1 to 10 m4. However, some species were found at 180 m5.
