Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules referred to as glass sponges. They are classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma. Glass sponges are uncommon and are found at depths from 450 to 900 metres although the species Oopsacas minuta has been found in shallow water while others have been found much deeper, they are found in all oceans of the world, although they are common in Antarctic and Northern Pacific waters. They are more-or-less cup-shaped animals, ranging from 10 to 30 centimetres in height, with sturdy lattice-like internal skeletons made up of fused spicules of silica; the body is symmetrical, with a large central cavity that, in many species, opens to the outside through a sieve formed from the skeleton. Some species of glass sponges are capable of fusing together to create bioherms, they are pale in colour, ranging from white to orange.

Much of the body is composed of extensive regions of multinucleate cytoplasm. In particular, the epidermal cells characteristic of other sponges are absent, being replaced by a syncitial net of amoebocytes, through which the spicules penetrate. Unlike other sponges, they do not possess the ability to contract. All Hexactinellid's have the potential to grow at different rates, but the average rate of growth is estimated to be around 32 centimeters long; some grow past that length and continue to extend their length up to 1 meter long. Estimated life expectancy for Hexactinellid who grow around 1 meter is around 200 years. One ability they do possess is a unique system for conducting electrical impulses across their bodies, making it possible for them to respond to external stimuli. Glass sponges like "Venus' flower basket" have a tuft of fibers that extends outward like an inverted crown at the base of their skeleton; these fibers are 50 to 175 millimetres long and about the thickness of a human hair.

Glass sponges are different from other sponges in a variety of other ways. For example, most of the cytoplasm is not divided into separate cells by walls but forms a syncytium or continuous mass of cytoplasm with many nuclei; these creatures are long lived. The shallow water occurrence of hexactinellids is rare worldwide. In the Antarctic two species occur as shallow as 33 meters under the ice. In the Mediterranean one species occurs as shallow as 18 metres in a cave with deep water upwelling The sponges form reefs off the coast of British Columbia and Washington State, which are studied in the Sponge Reef Project. Reefs discovered in Hecate Strait, BC have grown to up to 7 kilometres 20 metres high. Previous to these discoveries, sponge reefs were thought to have died out in the Jurassic period; the earliest known hexactinellids are from late Neoproterozoic. They are common relative to demosponges as fossils, but this is thought to be, at least in part, because their spicules are sturdier than spongin and fossilize better.

Like all sponges, the hexactinellids draw water in through a series of small pores by the whip like beating of a series of hairs or flagella in chambers which in this group line the sponge wall. The class is divided into five orders, in two subclasses:Class Hexactinellida Subclass Amphidiscophora Order Amphidiscosida Subclass Hexasterophora Incertae sedis Dactylocalycidae Gray, 1867 Order Lychniscosida Order Lyssacinosida Order Sceptrulophora Sponge reef Cloud sponge Sponge Reef Project Media related to Hexactinellida at Wikimedia Commons Data related to Hexactinellida at Wikispecies

1985 All-Ireland Under-21 Hurling Championship Final

The 1985 All-Ireland Under-21 Hurling Championship final was a hurling match, played at Walsh Park, Waterford on 25 August 1985 to determine the winners of the 1985 All-Ireland Under-21 Hurling Championship, the 21st season of the All-Ireland Under-21 Hurling Championship, a tournament organised by the Gaelic Athletic Association for the champion teams of the four provinces of Ireland. The final was contested by Kilkenny of Leinster and Tipperary of Munster, with Tipperary winning by 1-10 to 2-6; the All-Ireland final between Kilkenny and Tipperary was the fourth championship meeting between the two teams and their second successive meeting in an All-Ireland final. Kilkenny were hoping to retain the title for the second time in their history, while Tipperary were appearing in their seventh final in eight years. Tipperary's All-Ireland victory was their first since 1981; the win gave them fourth sixth All-Ireland title overall. Kilkenny's All-Ireland defeat was their fifth ever

Tamotsu Yatō

Tamotsu Yato was a Japanese photographer and occasional actor responsible for pioneering Japanese homoerotic photography and creating iconic black-and-white images of the Japanese male. He was a friend and collaborator of the writer Yukio Mishima and the film critic Donald Richie, as well as a long-term romantic partner of Meredith Weatherby, an expatriate American publisher and translator of Mishima's works into English. Yato completed three volumes of photography. Though Yato's work received only a limited public distribution, it has attained a cult following and has been acknowledged as a major influence by a number of artists working with male erotica. Thus, Sadao Hasegawa remarks in his Paradise Visions: "Tamotsu Yato achieved fame by creating Otoko, a picture book, he photographed Yukio Mishima, nude. His subjects: traditional, unsophisticated countryside men, are extinct today. Otoko was valuable because you could see these long-bodied, stout-legged, cropped hair, square-jawed men... Good-bye, men of Nippon!"

Siam Philharmonic Orchestra

The Siam Philharmonic Orchestra was founded in 2002 in Bangkok, under the name "Mifa Sinfonietta". At that time it was a small chamber ensemble devoted to bringing the discipline of the classical style to Thailand's classical musicians, it performed the works of Mozart and Haydn. In 2003, the orchestra gained its autonomy from MIFA, the music academy where it was born, was renamed the Bangkok Sinfonietta; however in 2004, it became clear that the orchestra was no longer a sinfonietta since it was now performing large-scale orchestral works by Brahms and Mahler. The Siam Philharmonic Orchestra is the resident orchestra of Opera Siam under the royal patronage of Princess Galyani Vadhana; the current artistic director is S. P. Somtow, guest conductors have included Linda Cummings; the current resident conductor is Trisdee na Patalung. The orchestra performs at the Thailand Cultural Centre; the Siam Philharmonic Orchestra's recording of Richard Strauss's Four Last Songs, with soprano Nancy Yuen, appears under the Orchid label.

It received second place in the independent JPF Awards in the opera category in 2006. In 2009 it began an initiative to perform the complete Mahler symphonies.
