Q. Scientists from India, Germany, United Kingdom and Switzerland have discovered a new family of bony fish named Aenigmachannidae from?

[A] Sunderbans

[B] Andaman & Nicobar Islands

[C] Eastern Himalayas

[D] Western Ghats

Answer: D
Notes:

Scientists from India, Germany, United Kingdom and Switzerland have discovered a new family of bony fish from the Western Ghats, and named it Aenigmachannidae.  

  • A year after the discovery of the enigmatic Gollum Snakehead, Aenigmachanna gollum from the rice fields of northern Kerala, scientists have now conducted detailed studies on its skeleton and genetic assembly. 
  • The study led to the recognition that this species, and its congener Aenigmachanna mahabali, represents a new family different from Channidae, in which both species were initially placed. 
  • Rendered images obtained from high-resolution CT scans revealed that Aenigmachanna gollum has a surprisingly large number of primitive characters, and detailed molecular phylogenetic analyses including of its mitogenome, suggested an ancient separation from Channidae, the study said. 
  • These suggest that members of Aenigmachannidae are “living fossils” and comprise an ancient gondwanan lineage that survived the break-up of the supercontinent and the northward drift of the Indian subcontinent, about 100 million years ago, it added.
