Tahitian prawns

Macrobrachium lar


Two dark gray-black crustaceans, about 6 inches long. The first pair of walking legs are long, spindly and tipped with claws.


Insular tropical montane valley stream.


Spotted in Waimano Stream in less than a foot of water. Unfortunately I did not have with me a camera that I could immerse in the stream. Consequently I could only acquire through-water imagery which is of poor quality owing to reflected sunlight. This species was introduced from the Marquesas decades ago as a food source, but the State Department of Land and Natural Resources has classified it as invasive because it successfully competes with native species.
