How is the pattern on the Wrought Iron Butterflyfish described?

Answer

A pale, reticulated network over a dark base.

The Wrought Iron Butterflyfish derives its common name from the appearance created by its specific pattern overlaying its dark body. The base coloration is very dark brown or black, serving as a canvas for a distinctive network of fine lines described as reticulated or net-like. These overlaying lines are pale, sometimes appearing grayish, bluish-gray, or yellowish-white. This structure is what evokes the image of intricate metalwork, setting it apart from species characterized by solid blocks of color or simple spots, highlighting an adaptation for complex visual environments rather than clear, open water.
