Not just a hazard to your score, but to your life. Mommy!
A half dozen Bull sharks got stranded in a small lake after a flood near Brisbane, Australia. It's said that they are fond of golf balls, birds and small mammals. The sharks are often seen trying to tempt the golf club members into the water, something about the joy of swimming.
The Bull shark, Carcharhinus leucas, also known as Zambezi shark or unofficially known as Zambi in Africa and Nicaragua shark in Nicaragua, is a shark common worldwide in warm, shallow waters along coasts and in rivers. The bull shark is well known for its unpredictable, often aggressive behavior.
The Bull shark is most famous for its remarkable ability to thrive in both saltwater and freshwater and can travel far up rivers. They have even been known to travel as far up as Indiana in the Ohio River and Illinois in the Mississippi River, although there have been few recorded attacks. As a result, they are probably responsible for the majority of near-shore shark attacks, including many attacks attributed to other species.
