A temporary exhibit at the Smithsonian’s National Museum of Natural History uses x-rays of fish from sharks to gar to study diversity in skeletal systems. The x-rays show that some fish have skeletons built from cartilage while others have skeletons built from bone. The exhibit is called “X-Ray Vision: Fish Inside Out”. The exhibit will be on display through August 5, 2012.
All the x-rays on exhibit are viable on flickr. You can read more on the exhibit here.

Pot-bellied seahorses have been successfully breeding at the NY Aquarium further strengthens the endangered species. This species of seahorses have a long history in traditional medicines which coupled with the pet industry has led it to near extinction. Currently the sales of the pot-bellied seahorse are prohibited under the Convention on International Trade in Endangered Species (CITIES) of Wild Fauna and Flora. With the new breeding program showing signs of success we may see tank raised specimens hitting the market in the coming years. The pot-bellied seahorse is one of the larger seahorse growing to a shocking 13.5 inches making it a nice specimen in home aquariums. More on the breeding program can be read here.
For aquascaping, this EcoPico setup, uses one coralline covered rock, which is slowly being taken over by a colorful selection of ricordeas and yumas. You’ll also see a neat collection of critters (extra credit for ID’ing the nudi at 1:12).

Orphek has stepped up their game, quickly racing towards the top of the LED aquarium lighting market. ReefTools recently introduced the Orphek PR-156 to our community, now we would like to introduce its big brother, the Orphek Nilus. The Nilus looks very similar to the PR-156 since Orphek maintained the stylish designed. The biggest changes are in the controller, it is now equipped with dimming functions capable of independently dimming the white and blue LEDs. This coupled with the controller’s timers gives the aquarist absolute control over the look of their reef. The controller can be programmed for multiple intensities through out the day creating a nice sunrise to sunset look. Orphek states the dimmer spent a year in research and design perfecting the fixtures ability to maintain the spectrum output while being dimmed. To obtain the “perfect” spectrum for SPS corals Orphek added additional diodes with varying colors. We are looking forward to the opportunity to see these in action.

A video was posted on YouTube last week showing an uncountable number of sharks migrating along the coast of Florida. The video was shot from a helicopter reportedly behind the Breakers Hotel in Palm Beach.

Kent Marine stated on their website yesterday, February 22, 2012, that there is a quality concern with the Reef Carbon manufactured between December 5, 2011 and February 8, 2012. Apparently heavy metals, like copper, found their way into the carbon during mining. These metals will have negative affects on clams and stony corals. It is reported these effects have been witnessed with in a couple of hours after using the contaminated carbon. You can read the full product advisory and review a chart showing which products have been affected here.

Nasa satellites have capture images of a giant underwater storm called an eddy off South Africa. The eddy stretches approximately 90 miles across and it was first spotted back in December. It was stated the storm poses no threat to sea life or shipping lanes, in fact it is believed the massive swirl will pull nutrient rich particles from the ocean’s floor to the surface. It could be Mother Nature’s way of spring cleaning.
Ecoxotic releases their new 18” Panorama Pro LED with the nano in mind. These little guys utilize three 19-watt Panorama Pro modules. Ecoxotic has maintained their sleek look and the ever convenient patented hinge mounting system. One of the best features of this fixture is the ability to customize it to your preference and the layout of your aquarium. An inline dimmer allows you to independently control the intensity and brightness of white and blue LEDs. Each of the modules can be shifted right to left to maximize the spread and focus of your aquascaping. The fixture leaves plenty of space to add additional Panorama Pro Modules or stunner strips to customize the look and spectrum.
