JAKARTA – A strange but real incident occurred in Australia, a flock of rare Bull Sharks stranded in a golf course lake. For nearly 20 years, a group of bull sharks have lived in an artificial pool on an Australian golf course. However, when the water recedes, this group of sharks disappears.
The Bull Shark’s habitat is unique because it can live in freshwater environments and is usually found in rivers throughout the world. Although their sojourn in freshwater is usually temporary, these sharks are sometimes trapped in freshwater environments for long periods of time and they can thrive.
These sharks can be in golf course areas because they are likely washed ashore during periods of flooding. High rainfall causes river water to overflow and inundate the surrounding plains. The golf course is less than 6.2 miles from the coast, so it is in the freshwater zone inhabited by Bull Sharks.
These Bull Sharks were first discovered in 1996. They were specially placed in a pool about 701 meters long and 381 meters deep. This measure is relatively small and shallow because it is not based on population calculations.
These sharks were also likely still juveniles when they were exposed, but eventually grew up to 3 meters long. The sharks were last seen in 2015. Flooding in 2013 may have caused some of the sharks to be released into nearby streams. Others may have died because a shark carcass was found in the golf course area.
Reporting from Live Science, Monday (2/10/2023), currently the pool is empty, this incident illustrates the adaptability of these ancient predators and their tolerance for freshwater environments. The research team said that the case of the Banten Shark in the pond is an example of the oldest shark ecosystem inhabiting an environment with low salinity.
