Appearance
Butterflyfish mostly range from 12 to 22 cm (4.7 to 8.7 in) in length. The largest species, the lined butterflyfish and the saddle butterflyfish, C. ephippium, grow to 30 cm (12 in). The common name references the brightly coloured and strikingly patterned bodies of many species, bearing shades of black, white, blue, red, orange, and yellow. Other species are dull in colour. Butterflyfish are a boundless, different group of marine percoids with delegates on practically all coral reef frameworks and in every single tropical ocean. Their bright and color patterns have drawn in much consideration, creating an abundance of data about their conduct and environment. Many have eyespots on their flanks and dark bands across their eyes, not unlike the patterns seen on butterfly wings. Their deep, laterally narrow bodies are easily noticed through the profusion of reef life.
