What was the name of Bhima's conch shell?

Bhima’s conch shell was named Paundra.

The name appears in Bhagavad Gita 1.15, during the dramatic opening of the Kurukshetra War. As the two armies prepare to fight, Krishna blows Panchajanya, Arjuna blows Devadatta, and Bhima blows his great conch, Paundra.

The verse identifies Bhima through the epithets Bhima-karmā, “performer of formidable deeds,” and Vrikodara, commonly explained as “wolf-bellied.” These descriptions reflect his enormous appetite, immense physical strength and fearsome reputation as a warrior.

Paundra is often confused with the other famous conches named in the same passage. Panchajanya belonged to Krishna, Devadatta to Arjuna, and Ananta-vijaya to Yudhishthira. Nakula and Sahadeva had conches called Sughosha and Manipushpaka. The spelling may also appear as Paundram or Poundra in different English translations, but Paundra is the standard English answer for Bhima’s conch.
