______________ are specialised pores that allow a shark to detect magnetic fields of moving organisms.

Directions: Read the given passage carefully and answer the following question.

The Great White Shark is the largest predatory shark, and is probably the most well-known and feared shark. The Great White Shark is gray or bluish above and white below. The largest Great White Sharks can reach lengths of 22 feet and weigh up to 5,000 pounds. Most are between 13 and 16 feet and weigh 1,500-2,400 pounds. The Great White Shark has massive teeth, which are positioned in rows and serrated. When the Great White Shark attacks, it bites its prey and shakes it head back and forth. The serrated teeth act as a saw and literally tear the victim apart. The Great White Shark often swallows many of its own teeth in an attack. The Great White Shark normally feeds on fish, seals, dolphins, porpoises, otters, and turtles. It is thought to locate its prey by electrosense and by smell. Like all sharks, Great White Sharks have special pores called Ampullae of Lorenzini, which enable them to detect the electromagnetic fields radiated by moving organisms. Great White Sharks can detect voltage as small as one half billionth of a volt.
