Spondylus Princeps
''Spondylus'' is a genus of bivalve molluscs, the only genus in the family Spondylidae.MolluscaBase (2019). MolluscaBase. Spondylus Linnaeus, 1758. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=138518 on 2019-03-04 They are known in English as spiny oysters or thorny oysters (though they are not, in fact, true oysters). Description The many species of ''Spondylus'' vary considerably in appearance. They are grouped in the same superfamily as the scallops. They are not closely related to true oysters (family Ostreidae); however, they do share some habits such as cementing themselves to rocks rather than attaching themselves by a byssus. The two halves of their shells are joined with a ball-and-socket type of hinge, rather than with a toothed hinge as is more common in other bivalves. They also still retain vestigial anterior and posterior ''auricles'' ("ears", triangular shell flaps) along the hinge line, a char ...

Mixtec
The Mixtecs (), or Mixtecos, are indigenous Mesoamerican peoples of Mexico inhabiting the region known as La Mixteca of Oaxaca and Puebla as well as La Montaña Region and Costa Chica Regions of the state of Guerrero. The Mixtec Culture was the main Mixtec civilization, which lasted from around 1500 BC until being conquered by the Spanish in 1523. The Mixtec region is generally divided into three subregions based on geography: the Mixteca Alta (Upper Mixtec or Ñuu Savi Sukun), the Mixteca Baja (Lower Mixtec or Ñuu I'ni), and the Mixteca Costa (Coastal Mixtec or Ñuu Andivi). The Alta is drier with higher elevations, while the Baja is lower in elevation, hot but dry, and the Coasta also low in elevation but much more humid and tropical. The Alta has seen the most study by archaeologists, with evidence for human settlement going back to the Archaic and Early Formative periods. The first urbanized sites emerged here. Long considered to be part of the larger Mixteca region, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smallpox
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
