Paracorophium sp.
Taxonomic Group: Crustaceans-Amphipods


Paracorophium sp. is an unidentified tube-building amphipod, which belongs to a genus endemic to the Southern Hemisphere. It occurs in fresh, brackish, and coastal marine waters in New Zealand, Australia, Chile, Palau, and Thailand. It has been introduced to estuaries in California where it extends from Humboldt Bay to Morro Bay. Humboldt Bay was involved in timber trade with Chile and New Zealand, so both are plausible source areas. Further taxonomic work is required to determine the true identity and origin of this species.
