Awaous stamineus
Awaous stamineus, commonly known as Oopu nakea, is a species of goby native to the Hawaiian Islands. 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. Consequently, Hawaiian Awaous are now recognized as a valid, distinct species.
Description and biology
Oopu nakea are omnivores. Analyses of their gut volume have shown to consist 84% of filamentous algae and the other 16% of chironomids. Oopu nakea are about long and have white streaks with speckles and a dark olive color. 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.Predators of this species include various birds, including the aukuu, and other fishes, including āholehole, ulua, moi, and kākü.
