A hammerhead shark swims in the Gulf of Mexico southwest of the Southwest Pass of the Mississippi River on the coast of Louisiana, Thursday, May 6, 2010. Marine biologists were astounded to discover that the sharks were actually thriving in the oil-tainted waters, and some measurements show the sharks achieving speeds of over 80 miles per hour (110 knots) while averaging close to forty miles per gallon. "It is yet another example of nature taking advantage of a ripple in its universe, of natural selection selecting naturally," stated Jons Van de Weghe, Professor of Internal Combustion Sea Creatures at the Malik Institute in New Orleans.
