The Mekong River's giant fish, some as big as grizzly bears, are facing a serious population decline.
Overfishing, along with habitat destruction from dams and climate change, are severely impacting their numbers.
These megafish are crucial for the river's ecosystem and the livelihoods of many people who depend on fishing.
Scientists are urging immediate action, including stricter fishing regulations and habitat protection, to prevent their extinction.
