Hawaiian mountain shrimp

About Hawaiian mountain shrimp

Atyoida bisulcata is a decapod crustacean in the family Atyidae. 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 stream shrimp; the state freshwater profile supports a life cycle linked to both streams and the sea. 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.
