The Washington State Department of Transportation is updating the Washington Aviation System Plan (WASP). The primary purposes of the WASP update are to: Study the performance and interaction of Washington's entire aviation system. Understand the contributions of individual airports to the system as a whole.
The hammerhead shark is found worldwide in tropical and warm coastal waters and near continental shelves. They may also be found in the adjacent coral reefs, lagoons and surrounding deep waters.
Using mitochondrial DNA, a phylogenetic tree of the hammerhead sharks showed the winghead shark as its most basal member. As the winghead shark has proportionately the largest hammer of the hammerhead sharks, this suggests that the first ancestral hammerhead sharks also had large hammers.
