Bigeyes in Hawaii
Bigeyes are red reef fish known for their large, reflective eyes. Their eyes help them see in dim places, which is useful because these fish often hide during the day and become more active at night.
In Hawaii, bigeyes are called 'aweoweo, meaning “glowing red.” The name fits well because many bigeyes have a bright red color and eyes that can shine when light hits them underwater. There are about 18 species of bigeyes worldwide, and several are found in Hawaiian waters. The Hawaiian Bigeye and Common Bigeye are the species most often connected with nearshore reef areas.
Where Bigeyes Hide and Feed
During the day, bigeyes usually stay in caves, reef cracks, ledges and shaded places. Their red color can look darker in deeper or shadowed water, helping them stay less noticeable. At night, they move out to feed on small planktonic animals.
Divers may spot bigeyes by looking carefully into reef shelters, but it is important not to reach into holes or disturb fish hiding there. On night dives, their eyes may reflect a bright flash of light, making them easier to notice.
Cultural Note
The red color of 'aweoweo also gave this fish cultural meaning. In old Hawaii, red was associated with ali'i, or royalty. One story connects large numbers of bigeyes seen near Pearl Harbor with the death of King Kalakaua in January 1891.
