What makes the brain of the shark so unique?

Try not to panic, but sharks can detect your heartbeat in the water. What’s actually happening is that these sea predators, as well as rays and skates, can respond to the heartbeat of their prey through their super-sensitive electro-sensory organs.

Myth #1: Sharks Must Swim Constantly, or They Die
Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
