* Fish: They are known to consume both small and large fish, including carp, catfish, and other bottom-dwelling species.
* Crustaceans: Crabs, shrimp, and other crustaceans are important sources of food for Mekong stingrays.
* Insects: They will also eat insects and larvae that they find on the riverbed.
* Worms: Earthworms and other worms are also part of their diet.
* Carrion: They are known to scavenge on dead animals, supplementing their diet with this readily available food source.
Their feeding habits are influenced by several factors:
* Size and age: Younger and smaller stingrays tend to eat smaller prey like insects and worms, while larger adults can consume larger fish and crustaceans.
* Habitat: The availability of specific prey items in different areas of the Mekong River will also influence their diet.
* Season: Their diet may vary depending on the availability of specific prey items throughout the year.
Mekong stingrays are crucial to the health of the Mekong River ecosystem. They play a vital role in maintaining a healthy balance by regulating fish populations and keeping the riverbed clean.
