Pinctada maxima

Pinctada maxima is a species of pearl oyster, a marine bivalve mollusk in the family Pteriidae, the pearl oysters. There are two different color varieties: the White-lipped oyster and the Gold-lipped oyster.

These bivalves are the largest pearl oysters in the world. They have a very strong inner shell layer composed of nacre, also known as "mother of pearl". They are important in the cultured pearl industry as they are used to produce South Sea pearls.

Known also as the South Sea Pearl or Philippine Pearl, it was declared by Philippine President Fidel Ramos as the national gem in 1996 through Proclamation No. 905. This is also featured at the reverse side of the PHP 1000 bill.

Distribution

This species occurs in Australia, Fiji, Tahiti, Indonesia and the Philippines.

Description

Pinctada maxima oysters grow very large, up to 12 inches in diameter. The two color varieties have different coloration in the outer edge of the interior. This mother of pearl or nacre is responsible for the color of the pearls that the oyster can produce. Water temperature, plankton and sediments determine which color variety is more common in a given area.

Pinctada

Pinctada is a genus of saltwater clams, marine bivalve molluscs in the family Pteriidae, the pearl oysters. These oysters have a strong inner shell layer composed of nacre, also known as "mother of pearl".

Pearl oysters are not closely related to either the edible oysters of family Ostreidae, or the freshwater pearl mussels of the families Unionidae and Margaritiferidae.

Pinctada maxima pearl oysters are the only oyster species that produces South Sea pearls. Currently they are cultured primarily in Australia and Tahiti. A pearl oyster can be seen on the reverse side of the 1,000 Peso bill of the Philippines.

Species of commercial value

All species within the genus produce pearls. Attempts have been made to harvest pearls commercially from many Pinctada species. However, the only species that are currently of significant commercial interest are:

Maxima (music)

A maxima, duplex longa, or larga (in British usage: large) was a musical note used commonly in thirteenth and fourteenth century music and occasionally until the end of the sixteenth century. It was usually twice or, rarely, three times (Stoessel 2009, 181) as long as a longa, four or six or nine times as long as a breve, and 8, 12, 18, or 27 times as long as a semibreve (whole note). Like the stem of the longa, the stem of the maxima generally pointed downwards except occasionally when it appeared on the bottom line or space. Before around 1430, the maxima was written with a solid, black body. Over the course of the fifteenth century, like most other note values, the head of the maxima became void (Apel 1961, 87).

In most early sources the duplex longa has twice the body of a longa, but before 1250 there is often no clear difference of shape and the presence of the duplex longa is instead merely suggested by a greater distance between the notes in the tenor (in score notation), caused by the greater number of notes in the upper parts (Apel 1961, 224, 245). See Mensural notation for examples.

List of The King of Fighters characters

The King of Fighters fighting game series, produced by SNK Playmore, includes a wide cast of characters, some of which are taken from other SNK games. The story takes place in a fictional universe in which an annual series of 3-on-3 or 4-on-4 fighting tournaments are held.

The first game in the series introduces the initial main character of the series, Kyo Kusanagi, a young Japanese fighter who is the heir to a powerful group of martial artists having pyrokinetic abilities. Kyo fights against the Kusanagi clan's enemies, his rival Iori Yagami, and the god Orochi and its human followers, among others. The first four games in the series revolve about these fights, while The King of Fighters '99 introduces a new story arc, revolving around K′, a young man who seeks to destroy the mysterious NESTS organization because they kidnapped him at an early age and stripped him of his past memories, so that they could force him to be a fighter under their control. In The King of Fighters 2003, a new character named Ash Crimson enters the tournament, to steal the powers of the clans who sealed the Orochi in the past for an unknown reason. A new group of antagonists, known as Those From the Past, also appears in the series; they want to obtain Orochi's power for the purpose of giving it to their unknown master.
