Q. What are Namalycastis solenotognatha and Nereis dhritiae, that were recently seen in news?
Answer: New marine worm species
Notes: Researchers from the Zoological Survey of India (ZSI) discovered two new marine worm species, Namalycastis solenotognatha and Nereis dhritiae, from the West Bengal coast. Namalycastis solenotognatha is named from Greek words meaning “channeled jaw,” referring to its unique jaw with many canals. This species survives in extreme, sulfide-rich, foul-smelling mudflats, mainly on decomposing mangrove wood and hardened clay. Nereis dhritiae is named after Dhriti Banerjee, the first woman Director of ZSI. It lives inside wooden dock piles on sandy beaches submerged during high tide.
