This is a very interesting article that raises some very novel questions. Namely, how do you preserve a very rare and already dead basking shark when it washes ashore in Australia? Well it is certainly much easier said than done. I wrote about this shark discovery last month, but this article brings a different focus to the find. Basking sharks are extremely rare. In the past 160 years, this shark has only been spotted a grand total of three times. MORE
Closely related are the seven “sand darts” species of the genus Kraemeria, which differ most notably in the elongated lower jaw adapted for burrowing and the smaller pectoral fins. [While it isn’t mentioned in the description of the genus, it is presumed that Parkraemeria is derived from Para- (Gr. “near”) and Kraemeria, alluding to the close relationship of these two.]The sand darts live in similar habitats as the ginpohaze, though with a more widespread tropical distribution. Rather than residing in vertical burrows, Kraemeria shallowly buries itself up to its eyes with sand in the same manner as Trichonotus,lunging out to grab passing zooplankton. The general similarities between these two unrelated groups are a striking case of convergent evolution, where similar ecological and behavioral traits have independently brought about similar morphological adaptations in unrelated lineages.

Orphek recently presented a new LED pendant, the Atlantik P300. Designed specifically for large aquariums, it can successfully replace HQi 1000 watt lamps! MORE
Hello all, I have a common Curacao reef scene for you today: a wild-looking colony of brown tube sponges, Agelas conifera, and a little sea bass hiding among them. Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/; meaning “pore bearer”). They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, and consist of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems MORE
A leaked picture from Ecotech Marine shows their new return pump, the Vectra L1.
From this image, we can see that it has a variable output, DC with the new Quiet Drive, and a transformer. I plan to connect this pump to my Vortech with a wireless Quiet Drive controller, which will make it so easy to control. MORE
Good morning gang, more weird weather today, the ocean is still a mess and the wind hasn’t stopped! We have another submersible run today scheduled at 11:15, and yours truly will be under the sea taking pictures, you might be able to see us at www.seesubmarine.com. I have a fun fish face for you today that I captured a few weeks ago on our Substation house reef. This is a beautiful parrotfish, shot during the day at F22, which created the non-distracting black background and lots of great details.MORE
Doing your aquascaping correctly from the beginning will help avoid hassles in the futureYour long-anticipated live rock shipment has finally arrived at your doorstep, and you can’t wait to get it in your tank and start watching as life emerges from those gnarly chunks. Though you’re understandably eager to forge ahead putting the rocks in place, it’s critical at this stage to give more than passing thought to how you should arrange them. Inappropriate aquascaping now can lead to major headaches—or at least less-than-satisfactory results—down the road. Here are five live rock aquascaping pitfalls you should take pains to avoid:1. Placing your rock structure atop the “shifting sands” If your system will include a substrate of any significant depth, the first layer of rocks should be placed either right on the tank bottom (or a thin cushioning layer of substrate) or atop some type of secure supportive structure (e.g., pilings constructed of PVC pipe, a framework of egg crate material, etc.). If placed directly on top of a deeper substrate, the rockwork can be easily undermined by burrowing/digging/tail-fanning fish or inverts, potentially resulting in a catastrophic rockslide. 2 MORE
