About blue-eyed rock crab

Percnon affine is a decapod crustacean in the family Percnidae. Published Kauaʻi evidence documents the species from Kauaʻi coastal/nearshore habitat. Evidence types include island checklist. These records establish a documented Kauaʻi occurrence but are not automatically interpreted as a present-day abundance estimate. The documented Kauaʻi habitat context includes rocky intertidal / nearshore. Current island persistence, abundance, and population trend were not established by the occurrence material used for this record. 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.
