A naga born to Kashyapa and Kadru. It was known to be intelligent. Once Vinata said that the tail hairs of Indra’s horse Uchaishravas were all white, Kadru maintained that it was black. It was agreed that whoever lost would become the other’s slave. As per Kadru’s instructions, a few nagas clung to the horse’s tail and made it appear black. Vasuki and a few others refused to support this and Kadru cursed that they would die in Janamejaya’s sarpasatra. A meeting was called by Vasuki, Shesha and others on how to avoid this. Elaputra made a long speech on this occasion as per Mahabharata Adiparva Chapter 38.
