THE SEA-RUN CUTTHROAT
The sea-run cutthroat is the semi-anadromous form of the coastal subspecies of the cutthroat trout (Onchorhynchus clarki clarki); semi-anadromous (or, synonymously, amphidromous) in that, after entering salt water, it stays relatively close to home and will sometimes re-enter fresh water for purposes other than to spawn.
