Australian scientists from James Cook University (JCU) have uncovered the secret to the wide distribution of golden jacks, a commercial fish species that lives in the Pacific and Indian oceans. It turns out that karangas learned to travel long distances thanks to whale sharks. The study was published on: area scientific institution.
Gold jack populations are found from the east coast of Africa to the west coast of North America and from southern Japan to northern Australia, according to oceanographers at JCU. The wide range says these fish somehow circumvent biogeographic barriers.
The science team found that the young Golden Trevally had also mastered hitchhiking with whale sharks, the largest living fish. Whale sharks migrate great distances, leaving a sparse area behind. Less water-resistance allows karangs tracking sea giants to expend less energy and travel to areas out of reach of their relatives.
