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.
