‘O’opu City

November 6, 2014

While working in the freshwater streams at Kalaupapa National Historical Park to collect data on the fish, shrimp, and snails, we ran into a virtual ‘o’opu city. There are two species of native ‘o’opu (gobies) in this video clip. They are ‘o’opu ‘alamo’o and ‘o’opu nōpili. Can you tell the difference? Can you tell the males from the females? The poster below can help you in your efforts.


This is what lives in Hawaii’s streams. Click to enlarge.

Watch out for the invasive Tahitian prawns. The ‘o’opu definitely do.

    Aloha I have a Ecology Class that I’m taking and we are currently interested in focusing on the Native Hawaiian stream species. Is it possible to receive one of these posters or have authorization for our Graphics department print out an enlargement to hang on our wall?
