Just Follow My Nose

In addition to olfactory receptors in a white shark's nose, the snout also is the site of a clustering of electroreceptors known as Ampullae de Lorenzini. As seen in this shot of Apollo-Orion, these sensory organs appear as black dots on the shark’s snout and consist of gel-filled pores. These sensory organs provide a sixth sense, which allows the shark detect electromagnetic fields.
