The bull shark is everywhere you wouldn't expect them to be. Bull sharks have a stocky figure and a broad flat snout. The bull shark is one of the 43 shark species that can live in saltwater and freshwater. That fact alone makes it one of the best known sharks. This species is known by several different names depending on where it is. It's called sometimes the Zambezi shark Nicaragua Shark or Ganges River Shark.
But this shark is also known as one of the top 3 most likely to attack humans. The Bull Shark is also named The Pit Bull of the Sea because of its aggressive behavior.
