Discovery highlights
New Marine Nematode Species Found Along Tamil Nadu Coast: Scientists from the Zoological Survey of India (ZSI) have discovered two new marine nematode species off the Tamil Nadu coast. These findings expand India’s marine biodiversity database and contribute to global taxonomic records.
The newly identified species are Corononema dhriti and Epacanthion indica. Their discovery reflects the unexplored richness of India’s coastal ecosystems.
Static GK fact: The Zoological Survey of India was established in 1916 and is headquartered in Kolkata.
Naming and classification
Corononema dhriti is named in honour of Dr Dhriti Banerjee, Director of ZSI. It is only the fourth known species of its genus globally, making it taxonomically significant.
Epacanthion indica derives its name from India and represents a unique addition to marine nematode diversity. Its classification highlights India’s contribution to global species identification.
Static GK Tip: Taxonomy is the science of classification of living organisms, developed by Carl Linnaeus.
Unique biological features
Corononema dhriti is a free-living marine nematode adapted to benthic environments, meaning it lives on or near the seabed. It plays a role in sediment-level ecological processes.
In contrast, Epacanthion indica has specialised mandibles and tooth-like structures, making it a microscopic predator. This feature places it higher in the benthic food chain.
Understanding nematodes
Nematodes belong to the phylum Nematoda and are among the most abundant organisms on Earth. They can be parasitic or free-living, depending on the species.
Structurally, they are elongated, bilaterally symmetrical, and taper at both ends. Many possess a pseudocoel, a fluid-filled body cavity aiding internal transport.
Static GK fact: Nematodes are found in extreme environments, including Antarctica, deserts, and deep oceans.
Ecological importance
Marine nematodes play a key role in nutrient cycling by decomposing organic matter. This process supports marine productivity and ecosystem stability.
They also act as bio-indicators, helping scientists assess environmental changes and pollution levels. Their presence reflects the health of marine ecosystems.
Additionally, they contribute to sediment stability, which is crucial for coastal ecosystem balance.
Significance for India
The discovery strengthens India’s position in marine research and biodiversity conservation. It also highlights the importance of studying lesser-known organisms.
Such findings support the broader goal of sustainable ocean resource management under initiatives like the Blue Economy.
