News– Researchers from the Zoological Survey of India discovered two new marine worm species along the polluted coastline of West Bengal.
These worms are “bio-warriors” that survive in extreme conditions where most life cannot, highlighting the delicate and often unseen biodiversity along India’s northern coasts.

About New Marine Worm Species
