The following list of freshwater fish species and subspecies known to occur in the U.S. state of Oregon is primarily taken from "Inland Fishes of Washington" by Richard S. Wydoski and Richard R. Whitney (2003), but some species and subspecies have been added from the Oregon Department of Fish and Wildlife (ODFW) website.
The gray wolf populations has been increasing in recent years and is monitored by the Oregon Department of Fish and Wildlife.

Tetraroginae, or Tetrarogidae, was first formally recognised as a taxonomic grouping in 1949 by the South African ichthyologist J.L.B. Smith. [1] The 5th edition of Fishes of the World treats this as a subfamily of the scorpionfish family Scorpaenidae, [3] however other authorities treat it as a valid family, the Tetrarogidae. [4]
Vespula pensylvanica, the western yellowjacket, is a Nearctic species of wasp in the genus Vespula. [1] [2] It is native to regions of North America, largely in areas with northern temperate climates. Its reproductive behavior is constrained by cold weather, which successfully reduces the number of western yellowjackets in cold months.
Many wasp lineages, including those in the families Vespidae, Crabronidae, Sphecidae, and Pompilidae, attack and sting prey items that they use as food for their larvae; while Vespidae usually macerate their prey and feed the resulting bits directly to their brood, most predatory wasps paralyze their prey and lay eggs directly upon the bodies ...
