What is the specialized feeding orientation indicated by the Arowana's large mouth and superior jaw alignment?
Answer
Surface hunting
The physical structure of the Arowana, characterized by its notably large mouth and a superior jaw alignment (where the upper jaw sits higher than the lower jaw), perfectly positions the fish for a specific type of predation. This structural arrangement makes them highly efficient at surface hunting. Consequently, their diet in the wild largely consists of prey items such as insects, smaller fish, crustaceans, and frogs that happen to be near or venture onto the water's surface.
