Description
The ’o’opu nākea is a native Hawaiian goby characterized by its mottled brown and tan coloration, perfectly camouflaged for its fast-flowing freshwater stream habitat. This amphidromous species migrates between freshwater and marine environments during its lifecycle, with adults residing in streams. They are known for their strong suction cup-like pelvic fins, which help them cling to rocks in strong currents.
