The smooth softshell turtle (''Apalone mutica'') is a species of softshell turtle of the Family (biology), family Trionychidae. The species is Endemism, endemic to North America. Geographic range ''A. mutica'' is native to North America. It is distributed throughout the central and southcentral United States as its geographic range extends from western Pennsylvania to New Mexico and south to the Florida panhandle. Smooth softshells turtles inhabit the Mississippi River drainage from Louisiana up to North Dakota and Pennsylvania, as well as the Colorado, Brazos, Sabine, and Pearl, Alabama and Escambia river systems. Two subspecies of ''A. mutica'' have been identified. The midland smooth softshell, ''Apalone mutica mutica'', is found throughout the central United States. The other subspecies, ''Apalone mutica calvata'', is found ranging from Louisiana to the panhandle of Florida. Habitat Both subspecies of ''A. mutica'' are typically found in medium to large unpolluted rivers wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French Natural history, naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle (''Apalone spinifera''), smooth softshell turtle (''Apalone mutica, A. mutica''), and common map turtle (''Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet bat ...

Roger Conant (May 6, 1909 – December 19, 2003) was an American herpetologist, author, educator and conservationist. He was Director Emeritus of the Philadelphia Zoo and adjunct professor at the University of New Mexico. He wrote one of the first comprehensive field guides for North American reptiles in 1958 entitled: ''A Field Guide to Reptiles and Amphibians of Eastern and Central North America'', in the Peterson Field Guide series. Biography Born in Mamaroneck, New York, Conant lost his father when he was young. When he was a teenager he took a job at a local zoo to help his mother make ends meet, which, along with participating in the Boy Scouts of America, began his lifelong passion for reptiles.

Spiny Softshell Turtle
The spiny softshell turtle (''Apalone spinifera'') is a species of softshell turtle, one of the largest freshwater turtle species in North America. Both the common name, spiny softshell, and the specific name, ''spinifera'' (spine-bearing), refer to the spiny, cone-like projections on the leading edge of the carapace, which are not scutes (scales). Description The spiny softshell turtle's scientific name is very descriptive of the animal. ''Apalone'' comes from the Greek word ''apalos'', meaning soft or tender, and ''spinifera'' is of Latin origin; ''spina-'' referring to thorn or spine and ''-ifer'' meaning bearing. This species is a member of the family Trionychidae, and one of the most distinguishing features of members in this family is the presence of a leathery, moderately flexible carapace. This is caused by loss of keratinized scutes and some bony tissue loss. Spiny softshell turtles have webbed feet, each with three claws. Another distinguishing feature of softshell ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
