The Kolekole Stream feeds ‘Akaka Falls and is home to one of the coolest fish species in the world, ‘the o'opu ‘alamo'o (lentipes concolor). This goby lays its eggs atop ‘Akaka Falls and, once hatched into a larval form, the fish make the floating journey down the falls to the Pacific Ocean. After a few months of hanging out in a planktonic state in the ocean, the post-larval fish swim 2.5 miles back upstream, traveling up numerous falls, including ‘Akaka Falls. How does this little goby make the vertical climb up the sheer cliff? Using a super-sucker disc and its strong pelvic fins. The fish will spend their entire adult life in the stream, laying eggs that will start the cycle over again.
