Great Seahorses

Why in news :

  • Extensive fishing off the Coromandel coast could be forcing the great seahorse to migrate laboriously toward Odisha.
  • Fishing is less intense in the Bay of Bengal off the Odisha coastline.
  • However, the shallow coastal ecosystem of the eastern Indian State may not be the new comfort zone for the fish with a horse-like head, a study published in the latest issue of the Journal of Threatened Taxa said.
