New River (Kanawha River)
The New River is a river which flows through the U.S. states of North Carolina, Virginia, and West Virginia before joining with the Gauley River to form the Kanawha River at the town of Gauley Bridge, West Virginia. Part of the Ohio River, Ohio River watershed, it is about long. The origins of the name are unclear. Possibilities include being a new river that was not on the Fry-Jefferson map of Virginia, an Indian name meaning "new waters", or the surname of an early settler. It was once called Wood's River for Colonel Abraham Wood, an English explorer from Virginia, who explored the river in the mid-17th century. Despite its name, the New River is one of the List of rivers by age, five oldest rivers in the world geologically. However, a claim that the river is the second oldest in the world is disputed by the West Virginia Geological and Economic Survey and the National Park Service. This low-level crossing of the Appalachians, many millions of years old, has long been a biog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambaridae
The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 species. Most of the species in the family are native to the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus '' Cambaroides'' are only found outside North America, as they are restricted to eastern Asia. A few species, including the invasive '' Procambarus clarkii'' and '' Faxonius rusticus'', have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct. A 2006 molecular study suggested that the family Cambaridae may be paraphyletic, with the family Astacidae nested within it, and the status of the genus ''Cambaroides'' remains unclear. The oldest fossils of the family are known from the Late Jurassic Morrison Form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
