Of these, Kaliya Naag was favored by Shri Krishna himself in his childhood and taken into his service, hence Shri Krishna was also the master of Kaliya. And Shankhapala protects the treasures of Mahalakshmi and Kuber. Dhritarashtra survived, Takshak and Kaliya survived, Takshak and Dhritarashtra, Takshak had personal enmity with Arjun, his family and kingdom were burnt by Arjun in Khandava forest, but one, Shri Krishna himself was riding on Arjun's chariot, Arjun had the support and blessings of Shri Krishna. Secondly, Arjun was the son of Devraj Indra and was a friend of Takshak Devraj, so on this occasion he did not consider it appropriate to go himself, had he gone, Shri Krishna would have killed him. So he sent Ashvasena, another serpent of his clan, who was looking for a chance to take revenge from Arjun.

If Takshak had not left his clan then Dhritarashtra himself would have had to descend, but Mahanag Dhritarashtra was born in Kurukula as Maharaj Dhritarashtra.
