Sharks hunt their prey using their strong sense of smell and by detecting electromagnetic fields generated by other animals. The great white shark's strongest sense is its ability to smell, and these sharks are able to detect a single drop of blood in ocean water. Sharks can detect electromagnetic fields through a series of pores on their snouts which feel for electric currents. This also aids sharks in navigating through oceans by following an electrical map created by the magnetic fields of Earth's crust.
More about sharks:
- The whale shark is the world's largest shark, and also its most gentle. It feeds on plankton by catching them in its open mouth.
- A shark's lifespan varies based on the species. Most live between 20 and 30 years; however, some species, like the whale shark, can live over 100 years.
- Typically, sharks hunt alone, but will hunt in groups for larger prey.
