"Bull Sharks Defy Expectations, Thrive in Freshwater for 17 Years"

A group of bull sharks has been living in a freshwater golf course pond in Australia for over 17 years, making it the longest observed instance of bull sharks surviving in freshwater. The sharks were likely stranded in the pond during severe floods in the mid-1990s. While the original sharks have not been spotted since 2015, it is unclear if they are still alive. The adaptability of bull sharks to different environments is highlighted by this unique case, and experts warn that with increasing extreme floods due to climate change, caution should be exercised around bodies of water that may have recently flooded.
