Sharks are really streamlined. They go faster than any other fish. Only porpoises can go faster. But porpoises are a mammal. Cheers, Ellen |

The eyes are out on the end of them. But their heads are still streamlined if you look at them from the front. They are like streamlined stalks or wings. It's sorta like having an extra set of fins like porpoises have on their sides where the arms used to be before they went back into the sea and evolved. But hammerheads have them on their heads. Cheers, Ellen |

The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. Ralph Liedert from the University of Applied Sciences, Bremen, Germany, is presenting his work on the application of artificial shark skin in a new anti-fouling strategy at the Society for Experimental Biology Annual Main Meeting in Barcelona [session A7.66]. Shark skin comprises scales that can flex individually from each other. Liedert produced a synthetic shark skin of elastic silicone, which has a significantly decreased contact surface. This reduced contact surface makes it harder for barnacles to attach, and reduces fouling by 67%. When applied to the ship hull, this artificial surface enables ships to ´self-clean´, and a speed of 4-5 knots would remove all organisms attached with little adhesion. Until recently, paints containing a biocide were used to prevent growth on submerged surfaces, but these were banned because of the the toxic effect of the highly toxic and unspecific biocide component on marine life. As barnacles, mussels and algae cause up to 15% increase in the drag resistence of ships, this research is providing an alternative anti-fouling strategy of great importance. Joe |
