How does a shark hunt for its food?
Sharks hunt with scent and sound. They will investigate loud noises or big objects for potential meals. Sharks have keen olfactory senses, located in the short duct between the anterior and posterior nasal openings, with some species able to detect as little as one part per million of blood in seawater. They can smell a drop of blood from miles away.Sharks generally rely on their superior sense of smell to find prey, but at closer range they also use the lateral lines running along their sides to sense movement in the water, and also employ special sensory pores on their heads (Ampullae of Lorenzini) to detect electrical fields created by prey and the ambient electric fields of the ocean.
