Red Seadragon Is Spectacular New Species

A paper in the Royal Society Open Science has announced the discovery of a new species of seadragon. The Ruby Seadragon (Phyllopteryx dewysea) is named for its incredible bright-red coloring and was first noticed after a male was caught during a biodiversity trawling survey in 2007. At first, scientists thought it was a weedy seadragon, but DNA analysis revealed it to be a completely new species. In addition to DNA research, the team also took a CT scan of one of the specimens. “[The] scan gave us 5,000 X-ray slices that we were able to assemble into a rotating 3-D model of the new seadragon,” said lead author Josefin Stiller. “We could then see several features of the skeleton that were distinct from the other two species, corroborating the genetic evidence.” The scientists believe the new seadragon has gone un-noticed for so long because it is found in deeper waters off the coast. The deeper water habitat may also explain its darker, red color

Bellevue H.S. Marine Science Lab Expands

The first (of three) coral study and propagation systems before it was filled with saltwater during setup.Last year I introduced you to David Bowers and the incredible marine science classroom laboratory he runs at Bellevue High School in Ohio, USA. Over the last 20 years, David and his students have transformed the humble classroom from a single modest aquarium to one of the best self-funded high school marine biology programs in the country. The classroom laboratory at this rural northern Ohio school features a 412-gallon mixed reef, 420-gallon bamboo shark research study tank, 250-gallon seahorse breeding study tank, several smaller student research project systems, and three new (not so small) additions. The new system(s) The three aforementioned additions are 8’ x 2’ custom-built (by Pentair Aquatic Eco-Systems) tanks that will be used for coral growth studies and propagation. These tanks (and tons of support equipment: sump, skimmer, heater, T-5 lights, return pump, circulation pumps, frag plugs, super glue, shipping bags/cups, and more) were generously donated by Rob McCoy of Fort Wayne, Indiana. Rob had been following the marine science club on Facebook and reached out with the thought that David and his students might be able to make use of this equipment. Currently, one of the systems is up and running with a few corals calling it home. David is now searching for branching Acropora or related SPS coral colonies, encrusting and plating corals, and LPS corals (particularly Fungia, Trachyphyllia, and Favidae)

Aging Bony Fish

When conducting studies, many ecologists are posed with the question: How old is this fish? Because size is rarely a fair indication of age, the use of a more precise method is often required. The most prevalent method of aging bony fish is known as Otolith Analysis. This procedure entails the extraction and microscope analysis of the fish’s otoliths – small calcium carbonate structures that are located slightly posterior to the fish’s eyes.

 These structures, which are used as gravity, balance, and movement indicators, grow continuously throughout a fish’s life and exhibit a unique growth pattern. This growth pattern is thought to be a result of seasonal temperature changes – during the winter, the otoliths grow slowly, accreting lightly-colored calcium carbonate; during the summer, the otoliths grow quickly, accreting darker calcium carbonate. The contrast between lighter calcium carbonate and darker calcium carbonate forms rings known as annuli. Since each annuli represents one year, scientists may determine the age of the fish by counting them.… More:

AquaNerd’s Top 10 Stories from 2014

Phew…2014 is almost over. And while it has been a fun year, it has also been an exhausting one. But, we made it, and we can look forward to the brand new adventures that await for us in 2015. Before we can move on, however, we must pay our respects to the passing year with a robust recap of the top 10 stories that were featured on the AquaNerd Blog during that time. So, without further adieu, here is our list of posts we got the most mileage out of.

Review: EcoTech RMS (Radion Mounting System)

Having already taken a look at EcoTechs gorgeous Radion XR15w Pro LED light in our recent unboxing review, we now turn our attention to their much-anticipated RMS (Radion Mounting System) which ties-in beautifully with the Radion Pro range and allows these lights to be elegantly suspended above even the most tricky of systems. As ever, the kit (XR15 version in our case) comes effectively packaged and all the parts are present and correct on initial inspection. After a quick skim of the simple instructions it obvious that we aren’t going to need a degree in rocket science to assemble this piece of kit, which is great. We are immediately and pleasantly surprised that some of the components here are metal, indeed the whole thing feels reassuringly heavy-duty compared to other brackets we’ve handled in the past. Somehow, the RMS still manages to look sleek and minimal though and it’s also nice to have thoughtful design features like integral cord management included. Overall the bracket also allows for a good deal of flexibility with the light able to slide back and to, or to be rotated on the X bracket (although this is primarily of use with the XR30)

Coral Therapy @ Design Miami 2014

For Design Miami/ 2014, we were honored to be asked to create a conceptual room in which we debuted ‘Coral Therapy’, a 360-degree virtual reality film experienced via the Oculus Rift. When viewing ‘Coral Therapy’, the viewer is enveloped by fluorescent corals and sea anemones; much like being inside a virtual planetarium theater. ‘Coral Therapy’ is designed to convey a virtual out-of-body experience in which the viewer is transported to a tranquil tropical reef in outer-space. An original ambient score enhances the cosmic coral perspective while accentuating the peaceful and relaxing experience. ‘Coral Therapy’ in action via Oculus Rift VR The Oculus Rift is not yet commercially available to consumers, so for Design Miami/ we utilized a developer’s kit prototype. When the commercial version is released in 2015, ‘Coral Therapy’ will be available to be purchased and experienced in high-definition resolution. A side view of the Curio Our Curio was developed in collaboration with Flying Pyramids, a Miami-based photographer and graphic designer. The walls featured innovative magnetic wallpaper installed by Visual Magnetics. The back wallpaper displayed a single macro photograph of the tentacles of a man-o-war, while the side wallpaper was of a brain coral fossil found in Miami Beach’s South Pointe Park. Magnetically overlaid on each of the sidewalls were six different color morphs of a new species of zoanthid soft coral that we discovered here in Miami. A looping film of flower anemones was displayed on the ceiling of the booth from a projector hidden within a mirrored dome that sat upon a hexagonal plinth crafted by Miami Industrial Arts, such that it reflected a full 360 image of the room. ‘Coral Therapy’ in effect via Oculus Rift VR We would like to thank Design Miami/ for inviting us to participate in the tenth edition of their prestigious show, along with the Knight Foundation for supporting our vision of elevating corals into the popular iconography of 21st century Miami as part of our ‘Coral City/Aquacultural Transformation’ project. Coral Morphologic Mission Statement: Coral Morphologic is a Miami-based art-science endeavor founded by Colin Foord and Jared McKay in 2007. Together we present coral reef organisms as archetypal life-forms via film, photography, site-specific installations, and multimedia artworks. Technological advances in the new millennium have enabled Coral Morphologic to explore a new frontier in the aesthetic interpretation of nature. In doing so, we have discovered corals to be the living embodiment of science and art converged. The combination of vibrant colors, fluid movement, geometric tessellation, and limestone architecture establish corals as the irrefutable icons of 21st century Miami. It is the remarkable ability of corals to adapt and evolve that inspires Coral Morphologic to establish them as the paradigm-shifting organisms of the global future. By elevating corals into the iconography of modern design and popular culture, Coral Morphologic entreats mankind to better understand and preserve Earth’s imperiled reef ecosystems through works that convey color and depth to the human experience.

Gorgonians Keep Growing In Acid Oceans

A new study, undertaken by an international team of scientists, suggests that Caribbean gorgonians may be more resilient to the ocean acidification levels forecast by the end of the 21st century than previously thought. The team, which includes experts from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, tested the effects of elevated CO2 concentrations on the growth and calcification rates of Eunicea fusca which is found throughout the Bahamas, Bermuda, South Florida and into the Gulf of Mexico. Although the species did show a negative response to calcification under elevated CO2 concentrations, growth and calcification did not actually completely stop under any of the CO2 levels used in the study. Specifically, the results also showed that although calcification dramatically declined at extremely high levels of CO2, this did not occur at moderately elevated levels.”Our results suggest that gorgonian corals may be more resilient than other reef-dwelling species to the ocean acidification changes that are expected to occur in the oceans as a result of climate change,” said Chris Langdon, UM Rosenstiel Professor and Director of the Coral Reefs and Climate Change Laboratory. “These findings will allow us to better predict the future composition of coral reef communities under the current “business-as-usual scenario.”

Visit at the Bellevue H.S. Marine Science Lab

David Bowers, science teacher at Bellevue High SchoolWhen I think back to my high school days, I remember a 29-gallon freshwater aquarium in science class. Coincidentally, I donated most of the specimens in that tank to my teacher from my home aquariums. It served as more of a stereotypical science classroom fixture than a teaching tool. So I guess you could say the hands-on aquatic learning experience was rather limited. The same certainly can’t be said of the Marine Science Lab at Bellevue High School in landlocked Ohio, USA. David Bowers’ classroom lab is an oceanic oasis amongst the fields of the Midwest (see the video below). Every time I visit Dave and his classroom, I’m struck by what a surprise it is to have thousands of gallons of salty learning opportunities at this small, rural school
