Scleropages jardinii, the Gulf saratoga, Australian bonytongue, pearl arowana or northern saratoga, is a freshwater bony fish native to Australia and New Guinea, one of two species of fishes sometimes known as Australian arowana, the other being Scleropages leichardti.

Except for duller coloration and smaller scale size, it appears very similar to the Asian arowana, S. formosus.

The depth of the bodies of adults is approximately 25–28% of the Standard Length, making this a more robust fish than its Australian cousin S. leichardti.

However, they can be easily distinguished from the Asian arowanas by identifying their red spotted fins & 7–8 rows of scales on their body.

Gulf saratoga are opportunistic carnivores, feeding on aquatic and terrestrial insects, small fishes and crustaceans.
