As a result of field work by associate professor James Davis Reimer and two graduate students from the University of the Ryukyus in Okinawa, Japan has found two new species of encrusting anemones, or colonial zoanthids, in unexpected locations. The species belong to the genus Neozoanthus, which was previously known only from a single species in the Indian Ocean. Surprisingly, the new species were found in the Pacific Ocean, in southern Japan and on the Great Barrier Reef, Australia. The study was published in the open access journal ZooKeys.
The only previous species of Neozoanthus was described in 1972 from Madagascar, and subsequently it was not seen for almost 40 years, until recent research had ascertained that new Pacific specimens likely belonged to Neozoanthus (Reimer et al. 2011, in the journal Marine Biology). The new study formally describes these new specimens as two species.
The members of this genus are small, with individual polyps no more than 6 mm in diameter, and have red, gray, blue or purple oral discs; all inhabit coral reef ecosystems in areas with strong currents and some siltation. Both new species and the species from Madagascar contain symbiotic, photosynthetic, single-celled algae that can provide them with energy from the sun.
"We were very surprised in 2008 to discover Neozoanthus in the Pacific, in Japan," said Reimer, "and initially thought that perhaps these were very rare." However, further research in southern Japan by graduate students Yuka Irei and Takuma Fujii, co-authors on the new paper, revealed that the Japanese species was locally common. A further surprise came during the Census of Marine Life's Census of Coral Reef Ecosystems (CReefs) surveys on the Great Barrier Reef in 2009 and 2010, when similar encrusting anemones were found thousands of kilometers away from both Madagascar and Japan.
"These findings can be explained by the fact that there are very few zoanthid researchers in the world. These species are not particularly hard to find, but there was no one looking for them," Reimer added. "This research demonstrates how little we know about marine biodiversity, even in regions relatively well researched."

It has long been understood that shipyards ? indeed the shipbuilding industry as a whole ? have been one of the most dangerous job sites in terms of risk of developing mesothelioma due to asbestos exposure.? Because the industry relied heavily upon materials laden with asbestos, hundreds of thousands of workers worldwide have succumbed to mesothelioma, lung cancer, asbestosis, and other asbestos related diseases.? A recent study of Italian shipbuilders at the shipyards in Monfalcone further confirms this tragic truth.
The crux of the matter is that your business would collapse without fully integrate marketing strategy though internet marketing is the only way to generate enough traffic to your website online. Similarly, Google has probably become the world's online library for research and as a source of information for anything under over around and inside the sun.
