The butterfly fish are remarkable with its arrays of patterns and colours and can be found in most oceans of the world especially on the reefs of the Atlantic Indian and Pacific Oceans. The butterflyfish, which are a group of tropical marine fish of the family Chaetodontidae, are pretty thin, small with a length of 12 to 22 cms, disk-shaped bodies with pointed noses.
The butterfly fish is named for their vivid coloured and patterns of their bodies. Some species appear in dull colour with patterns of blue, red, orange, or yellow striking backgrounds. A number of the fish wear dark bands crossing their eyes which help the fish to camouflage themselves from other predators, also round dots which appear on their flanks is an aid for being able to puzzle hunters. Worldwide, there are approximately 114 species of butterflyfish and look really like their cousins, the angelfish. However, the most common species is the four-eyed butterfly which can be found from New England to Caribbean.
Another recognised spot of the fish is their long thin snouts which are used to peck the coral animals in order to seek for coral polyps, worms and tiny invertebrates. The most common colours of the fish are yellow, white and black while pale yellow and whitish are found on the four-eyed butterfly. The banded butterfly usually wears black and white stripes across their bodies which resemble stripes of a zebra.Many of the butterflyfish mate for the whole life and if one dies, the other might die too. The fish always engrossed in plucking out the coral so it’s easy for you to follow them by swimming slowly
