During what some might say was a better than normal day at work, Robert Shadwick of the Scripps Company of Oceanography and his colleagues proceeded to go salmon shark fishing in the Gulf coast of florida Louboutin Pigalle of Alaska. After capturing specimens over 7 toes long and weighing above 300 pounds, the researchers proper temperatures throughout the sharks' bodies and also tested the mechanical power RM samples.
Their results, posted in the Oct. 27 publication of the journal Nature, showed that Cheap Ghd Australia Sale during 50 F, RM produced only 25 50 percent of the electricity it produced at Cheap Christian Louboutin Shoes Australia 79 F. The researchers concluded that RM temperatures below 68 F could permanently impair muscle perform.
National Science Foundation (NSF) system manager, Ione Hunt von Herbing said, "Knowing unique details about the anatomy plus physiology of salmon sharks delivers key insight into their ability to make such power and speed during boating. The knowledge Jeremy Scott Adidas Ebay could translate into greater designs for underwater cars."
The study was financed by NSF's integrative organismal biology program.
Salmon sharks are lamnids, a group of sharks that also contains the mako and great light. Numerous studies have shown that lamnid sharks as well as tunas share many anatomical along with physiological specializations that endow them their impressive swimming speed and memory. In contrast to other fish Christian Louboutin Outlet Australia the location where the RM is near the skin, this RM of these sharks and tunas is near the backbone. Mont Blanc Australia Refills Even though the ancestors associated with bony tuna and cartilaginous sharks diverged more than 300 million years ago, selection strain Mbt Sale Shoes for high performance swimming in every group seems to have occurred alone about 50 million yrs ago.
Throughout its life, Babyliss Australia Big Hair a new salmon shark never stops diving because it will sink. The body heat generated from continuous boating elevates the RM temperature, which, warms the surrounding white muscles and allows the shark to survive this frigid waters of the n . Pacific. If a shark stops going swimming, it could die from frosty exposure.
