This native shrimp was once a major food source of the Hawaiians when it was abundant in streams throughout the islands. Alien speices have reduced its populations, but it still survives in many places. Because of its ability to scurry up wet cliffs, it can scale the tallest waterfalls and is found in the highest streams in Hawai`i.
