Deepwater Pigments of The Red Sea

Together with an international team of researchers, divers from the University of Southampton, UK, Tel Aviv University and the Interuniversity Institute for Marine Sciences (IUI), Israel have found a colorful range of pigments in coral more than 50 meters below the surface of Red Sea reefs. Since only blue wavelengths from the sun reach coral at depths past 50 meters, the team was surprised to find specimens exhibiting pigments such as red and yellow. Jörg Wiedenmann, Professor of Biological Oceanography and head of the University of Southampton’s Coral Reef Laboratory, explains: “These fluorescent pigments are proteins. When they are illuminated with blue or ultraviolet light, they give back light of longer wavelengths, such as reds or greens.” 150624143152_1_900x600Dr Cecilia D’Angelo, Senior Research Fellow at Southampton sees a future for coral pigment use in industries such as biomedical adding: “We found, however, that some of the pigments of these corals require violet light to switch from their nascent green color to the red hue of the mature pigment. This is a particularly interesting property to develop markers for advanced microscopic imaging applications. Their optical properties potentially make them important tools for biomedical imaging applications, as their fluorescent glow can be used to highlight living cells or cellular structures of interest under the microscope. They could also be applied to track cancer cells or as tools to screen for new drugs.” Read more here!  … More:

Submarine Eruption Leads to Formation of New Red Sea Islands

Finding the right time, place and circumstances to observe the formation of a new island is pretty difficult. For one, it just doesn’t happen very often. It may occur in an inaccessible area. And, conditions in the water may quite dangerous. We recently reported on research of a newly formed island off of the coast of Japan. Now, researchers and videographers have been granted yet another such opportunity with volcanic events taking place beneath the Red Sea. A pair of six-mile-long and half-mile-wide troughs in the Earth’s crust have been spewing magma–creating new land–for weeks after a powerful submarine eruption. The result is a fresh land mass in the Zubair archipelago near Yemen. Scientists from King Abdullah University of Science and Technology of Saudi Arabia used satellite and video data to monitor the volcanic activity. The new islands have been given the names Sholan Island and Jadid Island. However, they won’t last very long–at least on a geological scale of time. Even the relatively mild wave action of the Red Sea is capable of causing considerable erosion. Judging from the rates observed in this area, both islands are expected to be leveled within a few hundred years. To view video and satellite imagery of the two islands published in Nature Communications please visit: http://www.nature.com/ncomms/2015/150526/ncomms8104/full/ncomms8104.html.… More:

The Sohal Tang: A Big, Belligerent Beauty

A Sohal Tang (Acanthurus sohal) grazing on algaeThe sohal tang (Acanthurus sohal) is one of many fish species available in the marine aquarium trade that should come with a warning label. It’s a gorgeous fish and generally very hardy, which is a plus, but anyone contemplating purchasing A. sohal should also be aware of its eventual size and often hyper-aggressive disposition. Physical traits A. sohal, which is found in the Western Indian Ocean, from the Red Sea to the Persian Gulf, is laterally compressed and ovoid in general shape. On its flanks and head, it exhibits narrow, horizontal, alternating light and dark stripes, which are vermiculated (wavy) around the head. The dorsal, anal, and pelvic fins are black while the pectoral and caudal fins are yellowish.

Orchid Dottyback: Hardy, Peaceful, and Just Right for Reef Tanks

Orchid Dottyback (Pseudochromis fridmani)Captive breeding of marine fishes has been a boon to our hobby in any number of ways, one of which is democratizing access to formerly really pricy species such as the orchid dottyback (Pseudochromis fridmani). While I wouldn’t characterize the current market price of this Red Sea species as “cheap,” it’s definitely in the realm of affordable for most hobbyists—and it’s hardiness, ease of feeding, manageable adult size, reef-friendliness, and relatively peaceful disposition (as dottybacks go, that is) more than justify the modest outlay of cash for a specimen. Physical traits P. fridmani is a small (reaching only around 2½ inches), streamlined fish with reddish-purple overall coloration and blue scale margins. A dark stripe extends diagonally from the snout upward through the eye. This species’ appearance in aquariums can vary markedly depending on the lighting scheme. Feeding You’ll find this P

Red Sea to Host Product Workshop at FJW Aquarium in Houston

We love aquarium related workshops, whether they be some sort of husbandry demo, a product showcase, or anything that spreads the good word of the hobby. We especially love them when the events are local. Such is the case for a Red Sea workshop that will be hosted at one of our favorite Houston area fish stores, FJW Aquarium. The event is still a little ways away, being hosted on September 20th from noon to 4pm. Like many events, this workshop will also feature awesome deals on livestock and equipment, as well as raffle prizes and other attractions that will bring in local hobbyists in droves. As we said, the workshop will take place at FJW Aquarium, located at 3839 Mangum Road in Houston, Texas. More details about the event will unfold on the FJW Facebook announcement, linked to above. A representative, or representatives, from Red Sea will be in-house doling out the goods on all of their latest gear, presenting a great opportunity for users to become more familiar with their dosing systems and other popular products.
