 Why in news

  • Scientists found the best-preserved coelacanth fossil, dating back 380 million years, from the Gogo Formation on Gooniyandi Country in northern Western Australia.

  • A study published in Nature Communications reveals that tectonic activity, not ocean conditions, drove the evolution of coelacanths over millions of years.

  • The new fossil species is named Ngamugawi wirngarri in honor of a respected Gooniyandi elder.

Coelacanths

  • Coelacanth, a giant fish regarded as an iconic example of a “living fossil.”

  • Coelacanths are elusive, deep-sea creatures, living in depths up to 2,300 feet below the surface.

  • These were thought to have gone extinct with the dinosaurs 65 million years ago. 

  • But its discovery in 1938 started a debate about how this lobe-finned fish fits into the evolution of land animals.

  • There are only two known species of coelacanths: 

    • one that lives near the Comoros Islands off the east coast of Africa, 

    • one found in the waters off Sulawesi, Indonesia.

  • Protection Status:

    • IUCN Status: Critically Endangered

      • Sulawesi Coelacanth is listed as ‘vulnerable’.

    • CITES Status: Appendix I
