The "spotted bonytongue" is a freshwater fish species scientifically known as Scleropages leichardti. It belongs to the Osteoglossidae family, commonly referred to as the bonytongues. This species is native to the rivers and freshwater habitats of Northern Australia, primarily found in the Gulf of Carpentaria region.
The spotted bonytongue gets its name due to the distinctive spots that cover its body. It possesses a long, elongated shape alongside a laterally compressed body, a defining characteristic of bonytongue species. This fish has a prominent jaw and a pair of significant pectoral fins.

Due to its striking appearance and impressive size, the spotted bonytongue is often sought after by hobbyist aquarists, leading to its capture for the aquarium trade. However, it is essential to note that the population of this fish is declining in the wild due to habitat loss, pollution, and overfishing. Conservation efforts are being implemented to protect and preserve the species.
