Final answer:
False. Sharks have well-developed sense organs that aid them in locating prey, including a keen sense of smell and the ability to detect electromagnetic fields.
Step-by-step explanation:
False. Sharks have well-developed sense organs that aid them in locating prey, including a keen sense of smell and the ability to detect electromagnetic fields. They have electroreceptors called ampullae of Lorenzini that allow them to detect the electromagnetic fields produced by all living things, including their prey. Sharks also have a sensory structure called the lateral line, which detects movement and vibration in the surrounding water. Therefore, when you stay still in water, sharks can still detect you.
