On average, sharks are responsible for six human fatalities per year, while humans annually kill tens of millions of sharks in fisheries. This jaw came from a commercial fishery driven by high demand for shark fins in overseas markets.

Story

Bull Shark by George Burgess

The Bull Shark is one of the big three that we’re concerned about in relation to shark attacks on humans, along with the White Shark and the Tiger Sharks. These are the animals that produce the largest and most dangerous incidents involving humans. Unlike the other two however, the Bull Shark is an animal that doesn’t live just in the marine world but in fact enjoys being in brackish waters and even ascends into freshwater. This particular species has been taken inland as far upstream as Illinois in the Mississippi River, just as an example. 

A worldwide species, it comes in contact then with humans readily in estuaries and river mouths as well as in the sea. It’s among the most aggressive of sharks – once it begins an attack it generally stays with its attack and continues on and on – and hence the name Bull Shark that was given to it. Pound for pound this is the shark that I would be most concerned about if I see it in the sea. White Sharks and Tiger Sharks, both of which get much bigger, are not as aggressive as the Bull Shark and therefore I wouldn’t be quite as concerned with them as others.

All in all, shark attack as a phenomenon is an uncommon situation with on average about six people dying per year worldwide in the sea. So, if you think about it, billions of hours being spent in the sea by humans every year, only six of us don’t come back out. And of those six, the bulls are probably responsible for about one third of those deaths.
