The Jardini Arowana also known by many other common names like Australian Arowana, Gulf Saratoga and Australian bonytongue are similar like their South American cousins, they are sometimes referred to as "water-monkeys" due to their unique predatory behavior where they will hide, stalk, and jump out of the water to ambush insects and small animals that are just passing by or hanging out on an overhanging branch or nearby vegetation.

Indigenous to the Jardine and Adelaide Rivers of northern Australia, Jardini Arowana can be found from still billabongs to flowing streams. They are large, highly evolved, powerful predators and can be traced back millions of years without many changes earning them the title, "living fossil".
