Alasmidonta Raveneliana
The Appalachian elktoe (''Alasmidonta raveneliana'') is a species of freshwater mussel in the family Unionidae, the river mussels. It is native to the United States, where it is known only from North Carolina and Tennessee. Description The Appalachian elktoe has a "thin, kidney-shaped shell, reaching up to about 10 centimeters (4 inches)." Younger mussels normally have a yellowish-brown periostracum (outer shell layer), while more mature mussels generally have a dark brown to greenish-brown periostracum. Features on the outer shell of the mussel, whether juvenile or adult, are often fine or hard to distinguish. In some cases streaks or waves are apparent, which are most easily noticeable on the dorsal region of the outer shell. Most individuals however have green waves, which are a similar hue as the rest of the shell and are often minute. Inside the shell, the nacre has a sheen which is white, blue, and silver. The center of the inner shell changes from a light, almost tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Muséum ...

Alasmidonta Varicosa
The brook floater (also known as swollen wedgmussel), ''Alasmidonta varicosa'', is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. It measures 25.1 mm to 80.2 mm in length although other research also suggests it rarely exceeds three inches (75 mm). Distribution This species is found in Canada (New Brunswick and Nova Scotia) and northeastern United States (Connecticut, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, Vermont, Virginia and West Virginia); It was formerly found in Rhode Island and four watersheds in Massachusetts but are now extinct in Rhode Island and almost extinct in Massachusetts. 1897 Research by Arnold Edward Ortmann showed it to be common in the Delaware and Susquehanna Rivers.

Triangle Floater
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC. In Euclidean geometry, any three points, when non- collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted. Types of triangle The terminology for categorizing triangles is more than two thousand years old, having been defined on the very first page of Euclid's Elements. The names used for modern classification are eit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
