Islands of Wonder
The Gobies’ Ascent to Safety
Hawaii’s upland rivers provide a safe haven from predators for young gobies while also acting as a resource for food. To access these waters, gobies must face a treacherous climb, pulling themselves up an enormous waterfall using the suction from their mouths and fins. The journey can take days and around 99 percent of these tiny fish perish before they reach the top.
