State Park
State parks are parks or other protected areas managed at the sub-national level within those nations which use "state" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, some of the political divisions of Mexico#States, Mexican states, and in Brazil. The term is also used in the Australian states of template:state parks of Victoria, Victoria and state parks of New South Wales, New South Wales. The equivalent term used in Canada, Argentina, South Africa, and Belgium, is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies. State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., r ...

Shark Tooth
Sharks continually shed their teeth; some Carcharhiniformes shed approximately 35,000 teeth in a lifetime, replacing those that fall out. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. The type of tooth that a shark has depends on its diet and feeding habits. Sharks are a great model organism to study because they continually produce highly mineralized tissues. Sharks continually shed their teeth and replace them through a tooth replacement system. Through this system, sharks replace their teeth relatively quickly with replacement teeth that are ready to rotate because their teeth often get damaged while catching prey. They will replace teeth that are broken and young sharks can even replace their teeth weekly. Although sharks constantly shed their teeth, factors such as water temperature affect the turnover rate. While warmer water temperatures produced faster rates, cold water temperatures slowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cibicides
''Cibicides'' is a genus of cosmopolitan benthic foraminifera known from at least as far back as the Paleocene ( Loeblich & Tappan, 1988) that extends down to the present. The test, or shell, of Cibicides, which is commonly found attached, is multichambered, plano-convex, trochospiral, with a flat or dished-out evolute spiral side and a strongly arched, involute umbilical side. The test wall is calcareous, perforate, bilamellar, with a radial microstructure. The flat or nearly flat spiral side is coarsely perforate while the arched umbilical side is finely perforate. The apertural face and peripheral keel, where the two faces meet, are imperforate. Sutures on the spiral side are thickened and may be elevated, but are narrow and depressed on the umbilical side. The aperture a low interior-marginal equatorial opening that extends a short distance onto the umbilical side but continues along the spiral suture on the spiral side. ''Cibicides'', named by Montfort, 1808, is included i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
