Description
The foureye butterflyfish (Chaetodon capistratus) is a butterflyfish (family Chaetodontidae). It is alternatively called the four-eyed butterflyfish. This species is found in the Western Atlantic from Massachusetts, USA and Bermuda to the West Indies and northern South America. Foureye butterflyfish are deep-bodied and laterally compressed, with a single dorsal fin and a small mouth with tiny, bristle like teeth. The body is light grey, sometimes with a yellowish hue, and dark forward-pointing chevrons. The ventral fins are yellow. The species gets its common name from a large dark spot on the rear portion of each side of the body. This spot is surrounded by a brilliant white ring, resembling an eye. A black vertical bar on the head runs through the true eye, making it hard to see.
