Hawaiian river prawn

About Hawaiian river prawn

Macrobrachium grandimanus is a decapod crustacean in the family Palaemonidae. Published sources characterize its origin status as endemic Hawaiian. Published Kauaʻi evidence documents the species from Limahuli Stream. The cited evidence includes records dated or referenced to 1989. Evidence types include biological survey. These records establish a documented Kauaʻi occurrence but are not automatically interpreted as a present-day abundance estimate. The documented Kauaʻi habitat context includes freshwater stream and amphidromous stream-to-sea life cycle. For current-status context, current Kauaʻi presence supported by state freshwater species information. A native amphidromous river prawn documented from Kauaʻi streams. The available Kauaʻi evidence does not support adding island-specific claims about diet, reproduction, behavior, population size, or trend unless those points are stated in the cited sources, so they are not inferred here. Keeping the accepted taxonomic concept together with the dated occurrence evidence allows later surveys to distinguish historical documentation from contemporary status.
