Mysterious Disappearance: Bull Sharks Vanish from Golf Course Pond After 20 Years

A group of bull sharks lived in an artificial pond on an Australian golf course for nearly 20 years after being stranded by receding floodwaters. The sharks, which were likely washed inland during flooding, were first detected in 1996 and grew up to 9.8 feet long. Their presence became a mascot for the golf course, but they were last seen in 2015. It is believed that some may have escaped during a flood in 2013, while others may have died. This case highlights the adaptability of bull sharks and their ability to tolerate freshwater environments, making it the longest known example of bull sharks continuously inhabiting a low-salinity environment.
