Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks that only two khaṇḍas of the Kūrma Purāṇa are now available, namely the Pūrva-khaṇḍa and Uttara-khaṇḍa. Sometimes it is said that the Kūrma Purāṇa contains six thousand verses, but originally the Kūrma Purāṇa contained seventeen thousand verses. According to Śrīmad-Bhāgavatam, there are seventeen thousand verses in the Kūrma Purāṇa, which is one of the eighteen Mahā-purāṇas. The Kūrma Purāṇa is considered the fifteenth of these Mahā-purāṇas.
