River otters as a whole look quite similar to weasels. This plan takes a unique approach toward restoring migratory fish by planning for the entire watershed rather than addressing one project at a time. If one-thousandth (or more) of the weight of water is from salt, then the water is "saline." Improved spawning and rearing habitat in the Eel River headwaters. The giant otter is native only to the Amazon, Orinoco, and La Plata river systems in South America. These include 79 invertebrates, 40 fishes, and 4 amphibians.
