Why do we need parrotfish ?
| || |
Parrotfishes play an important role in the growth of the coral reef .they eat algae that could smother the coral if they did not eat it.
The parrotfish feeds by swimming head down and scrapping algae as it glides in the the water. The parrotfish also bites off big portions of the coral, which it grinds up with specialized teeth. It is unsure if the parrotfish does this to eat the coral polyps or to extract algae .
Changing sex ?! : Parrot fish changes its sex throughout life-cycle . Female parrot fish lays eggs and when they become older , they transform in to the males . Parrotfish transformation is very visible : Light colour female transforms into dark coloured male !Parrotfish males will have bulging forehead ! If there is a loss of a male in group , female will change sex within few weeks ! Normally the largest female . Some male parrot fish maintain harems of females. If the dominant male dies, one of the ig females will change sex and color and become the male.
Parrotfish change sex , because many of them die young . So when all the females release their egg , there are only few males to fertilize them !

Measuring more than 4 feet in length and at 100 pounds, bumphead parrotfish from the Indo-Pacific are the family's largest member found .
Parrotfishes produce tons of coral reef sand each year. The sand-making process begins as the fishes graze on the algal film that grows on coral rock. To feed on the algae, the fishes munch on pieces of coral.
Teeth in their throats grind the coral, which then travels through their digestive systems and is deposited in the reef as white coral sand.
Parrotfishes swim by rowing themselves along with their pectoral (side) fins.
