When a fisherman caught a bull shark recently off the Florida Keys, he came across an unlikely surprise: One of the shark’s live fetuses had two heads. The fisherman kept the odd specimen, and shared it with scientists, who described it in a study published online today (March 25) in the Journal of Fish Biology. It’s one of the very few examples of a two-headed shark ever recorded — there about six instances in published reports — and the first time this has been seen in a bull shark, said Michael Wagner, a study co-author and researcher at Michigan State University.

The Uphill Road to Protecting Mexico's Bull Sharks

In Playa del Carmen, some conservation efforts have focused on stopping one man: Humberto Anduze Trujillo from nearby Puerto Morelos. Anduze is the only active shark fisherman in the area, according to the National Commission of Aquaculture and Fishing (CONAPESCA), but critics say his fishing alone is tangibly affecting the local bull shark population. Photos in which he poses proudly next to his day’s catch have spread over the Internet in recent months, enraging many.

Think golf’s too boring a game? Then get down to Australia, slick, and play the Carbrook Golf Club in Queensland. The water hazard there features up to 30 real live sharks.

The sharks were thought to be a myth for many years, but as you can see, that’s no myth. Club officials speculate that the bull sharks, some of which are estimated at up to 10 feet long, washed into the lake during a flood in the early 1990s.

Bull sharks 'have strongest bite out of all species

Relative to their body size, bull sharks bite harder than other, larger predatory sharks. 

A study of their jaws and jaw muscles has shown that adult bull sharks can bite with a maximum force equivalent to 6,000N. 

Maria Habegger of the University of South Florida in Tampa, US and colleagues in the US and Germany examined bite forces produced by 13 species of shark and their close relatives. 

Yes, we do have sharks well inland from the Atlantic Ocean

Interesting article about bull sharks in North Carolina’s Pamlico River:

My answer usually surprises them when I tell them that,“Yes, we definitely have sharks here on the Pamlico River and I wouldn’t be surprised if you find sharks well upstream of our brackish water.”

The next question that’s asked after I opine that we do have sharks here is, “What kind of sharks are here?”

When I reply that one of the major sharks we find in our brackish water is the bull shark the visitors begin to look a little concerned. “Isn’t that one of the sharks that is considered to be a man-eater?” The answer is that, Yes, they are and before you ask the next question I’ll tell you that, yes, we have had one well documented shark attack in these waters but that’s the only one I know of.
