Here's what we know:
* Fish: The Ganges shark likely consumes a variety of fish species found in the Ganges River, including catfish, carp, and other smaller fish.
* Other invertebrates: There is evidence suggesting they may also eat crustaceans and other invertebrates.
* Limited information: Because the Ganges shark is so rare and difficult to study, there's limited information about its specific diet.
It's important to remember that the Ganges shark is an apex predator in its ecosystem, playing a crucial role in maintaining balance. Their diet helps to control fish populations and keep the river ecosystem healthy.
