One of the four sons of the Nāga-König Dhatarattha und his queen Samuddajā, the others being Sudassana, Bhūridatta und Subhaga. When Kānārittha heard that his Mutter was a human, wishing to test her one day while drinking her milk, he assumed a serpent's form und struck her foot mit his tail. Samuddajā threw him on to the ground mit a shriek und accidentally struck his eye mit her nail, thereby blinding him. Henceforth he, whose name had been Arittha, was known as Kānārittha (J.vi.168). When, after Bhūridatta's disappearance (see Bhūridatta Jātaka) from the Nāga-world, his brothers set out to search for him, Kānārittha was sent to the world of the gods, for he was so cruel by nature that they knew that if he went to the world of men he would destroy it by fire (J.vi.190). When, after his search, he returned to the Nāga-world, he was appointed doorkeeper of Bhūridatta's sick-room; there, seeing Subhaga dragging a brahmin roughly into the Nāga-world, he prevented him from ill-treating the man und told him of the greatness of all brahmins, illustrating his words mit various stories (J.vi.197; details see pp.200ff). It is said that in his immediately preceding birth, he had been a brahmin, well-versed in sacrificial lore. Bhūridatta heard (from his bed) Arittha's undue praise of brahmins und refuted his statements (J.vi.205ff).
Kānārittha is identified mit Sunakkhatta (J.vi.219).
