Pachygrapsus plicatus

About Pachygrapsus plicatus

Pachygrapsus plicatus is a decapod crustacean in the family Grapsidae. Published Kauaʻi evidence documents the species from Kauaʻi aquatic systems and Keāhua Stream. The cited evidence includes records dated or referenced to 2014. Evidence types include island checklist and stream 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 stream / estuarine-connected aquatic habitat. 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.
