around their head called ampullae of Lorenzini. These are jelly filled pores that go down to the nerve receptors at the base of the dermis. They are specialized electroreceptor organs that allow the shark to sense electromagnetic fields and temperature changes in the water column.

What shark has the best senses?
SMELL The most acute sense of the Great White Shark is smell. They are able to detect substances of about 1 part per 10 billion parts water.

Do sharks sleep?
Sharks can sleep, and often opt to keep their eyes open while they do, according to new research published in Biology Letters. Because some sharks must swim constantly to keep oxygen-rich water flowing over their gills, it has long been rumored that they don’t snooze at all.
What do sharks see humans as?
“White sharks are often portrayed as ‘mindless killers’ and ‘fond of human flesh,’ however, this does not seem to be the case, we just look like their food,” study lead author Laura Ryan, a neurobiologist and post doctoral researcher at Macquarie University in Australia, told Live Science in an email.
