Direction: Read the passage carefully and answer the following questions.
The great white shark is larger, faster, and more dangerous than most. It can reach a length of 20 feet and weigh 70,000 pounds. Though its preferred diet is seals and dolphins, this fearsome fish regularly attacks almost any type of warm-blooded animal. In its snout are small holes that lead to receptors. These receptors pick up electrical nerve signals in the prey. The shark also has other sensors that detect blood in the water. Very rare in tropical or polar regions, great whites patrol mainly temperate ocean coastlines. The body is designed for efficiency in the water. It is broad in the middle and tapered at the ends for streamlined movement. Wing like pectoral fins provide lift and stability. Oil stored in the liver adds buoyancy. The tail fins are vertical and act as a rudder for fast turns. Amazingly it never stops swimming. All sharks are fish and most are carnivores. The great white is the world’s largest predatory shark. The whale shark is nearly twice as big, but like a baleen whale, eats mainly plankton.
