Description
The Longfin Smelt (*Spirinchus thaleichthys*) is a slender, silvery, anadromous fish native to the Pacific coast of North America. Known for its relatively long pectoral fins, it spends most of its life in marine waters, migrating to freshwater estuaries and rivers to spawn. It is a coldwater species that feeds on zooplankton and small invertebrates.
