Jardini Arowana (Scleropages jardinii)

Jardini arowana belongs to a different genus entirely than the South American silver arowana, hailing instead from Australia and New Guinea — and that split-continent distribution among bony-tongue fish is actually a living echo of the ancient supercontinent Gondwana breaking apart, stranding related lineages on drifting landmasses that eventually became separate continents.
