Awaous stamineus, commonly known as ‘O‘opu nakea, is a species of goby native to the Hawaiian Islands.[2] It has been previously considered a synonym of Awaous guamensis but recent work based upon morphological and genetic differences has recognized Hawaiian populations as being distinct.[3] Consequently, Hawaiian Awaous are now recognized as a valid, distinct species.[2][4]

Description and biology
‘O‘opu nakea are omnivores. Analyses of their gut volume have shown to consist 84% of filamentous algae and the other 16% of chironomids (non-biting midges).[5] ‘O‘opu nakea are about 14 inches long and have white streaks with speckles and a dark olive color.[6] They lay eggs downstream where the males and females guard the nest. The males make the nest and attract the females who then lay one clutch a year.[7]
Predators of this species include various birds, including the ‘auku‘u (black-crowned night heron), and other fishes, including āholehole (dark-margined flagtail), ulua (trevallies), moi (Pacific threadfin), and kākü (great barracuda).[8]

Human use and cultural significance
