Bull Shark
Because of these characteristics, many experts consider bull sharks to be the
most dangerous sharks in the world. Historically, they are joined by their more
famous cousins, great whites and tiger sharks, as the three species most likely
to attack humans.

Sand Tiger Shark
Like all sharks, sand tiger sharks breathe underwater, through their gills. But
sand tigers have one unique habit: They are the only sharks that come to the
surface to gulp air. This gulp of air isn't for breathing, though. After the
shark swallows the air it ends up in its stomach. The air makes the shark more
buoyant, so it can float motionless in the water as it watches for prey.
