Physical description
Adults have a very different pattern and colors. They have an eye band or dark line on their body that runs across the eye. This eye band actually makes the fish look like it is wearing a black mask. This mask confuses predators making them wonder which end is which. Predators don't know whether to attack the front end or the back. Adults can grow up to 13 inches (40 cm) long.

Location in the world
Indian and Pacific Oceans, from the Red Sea to Hawaii and the Austral Islands


Like two different fish, adult and juvenile emperor angelfish look completely different. It was once thought that the two forms were two completely different species. The body of the juvenile is a dark bluish black. It has a light blue line near the tail with a white circle around it. This white circle is surrounded by alternating light blue and white incomplete circles. When the juvenile reaches a length of 5 inches (12 cm), the colors completely change.
