(is it one Mahākalpa?).
I don't know for sure, but I rather suspect that the watery worms who preserve Mahayana sūtras will probably have rather short life-spans on that account.
It's reported, however, that the superior classes of nāgas can live for immensely long spans. Take Mahākāḷa, for example:
Mahākāḷa.– A Nāga king who dwelt in the Mañjerika Nāgabhavana. When the Buddha, after eating the meal given by Sujātā, launched the bowl up stream, it travelled a short way and then stopped, having reached the Nāga’s abode under the Nerañjarā, and then came into contact with the bowls similarly launched by the three previous Buddhas of this world-cycle. To the Nāga because of his long life it seemed that the previous Buddha had died only the preceding day, and he rejoiced to think that another had been born. He went therefore to the scene of the Buddha’s Enlightenment with his Nāga maidens and they sang the Buddha’s praises. J.i.70, 72; this incident is among those sculpturally represented in the Relic Chamber of the Mahā Thūpa (Mhv.xxxi.83); see also Dvy.392; Mtu.ii.265, 302, 304.
Kāḷa’s life span was one world-cycle; therefore he saw all the four Buddhas of this world-cycle, and when Asoka wished to see the form of the Buddha, he sent for Mahākāḷa, who created for him a beautiful figure of the Buddha, complete in every detail (Mhv.v.87 f; Sp.i.43, etc.)
When the Buddha’s relics, deposited at Rāmagāma, were washed away, Mahākāḷa took the basket containing them into his abode and there did them honour until they were removed, against his will, by Soṇuttara. Mhv.xxxi.25 ff.

That's also the case in the Pali Vinaya (and other Vinayas too, I believe). The origin story about the prohibition against ordaining animals was the result of the sangha ordaining a nāga who had assumed human form:
The Story of an Animal (Tiracchānagatavatthu)
Now at that time a certain serpent was troubled about his birth as a serpent, he was ashamed of it, loathed it. Then it occurred to that serpent: “Now, by what means could I be freed quickly from birth as a serpent and get back human status?” Then it occurred to that serpent: “These recluses, sons of the Sakyans, are dhamma-farers, even-farers, Brahma-farers, they are truth-speakers, they are of moral habit, of good conduct. Now if I were to go forth among the recluses, sons of the Sakyans, so would I be freed quickly from birth as a serpent and could get back human status.”
Then that serpent, in the form of a brahmin youth, having approached the monks, asked for the going forth. The monks let him go forth, they ordained him. Now at that time that serpent, together with a certain monk, was living in a dwelling-place on the boundary. Then that monk, getting up in the night towards dawn, paced up and down in the open air. Then that serpent, confident that that monk had gone out, fell asleep. The whole dwelling-place was full of the snake, his coils were protruding through the windows.
Then that monk, thinking: “I will enter the dwelling-place,” opening the door, saw the whole dwelling-place full of the snake, his coils protruding through the windows. Terrified at seeing this, he uttered a cry of distress. Monks, having run up, spoke thus to that monk: “Why did you, your reverence, utter a cry of distress?”
“Your reverences, this whole dwelling-place is full of a snake, his coils are protruding through the windows.” Then that serpent having awakened because of this noise, sat down on his own seat. Monks spoke thus: “Who are you, friend?”
“I am a serpent, honoured sirs.”
“But why did you, friend, act in this way?” Then that serpent told this matter to the monks. The monks told this matter to the Lord.
Then the Lord on this occasion, in this connection, having had the Order of monks convened, spoke thus to this serpent: “Indeed, you serpents are not liable to growth in this dhamma and discipline. You, serpent, go away, observe the Observance day precisely on the fourteenth, fifteenth and eighth day of the half-month. Thus will you be freed quickly from birth as a serpent and get back human status.”
Then that serpent, thinking: “It is said that I am not liable to growth in this dhamma and discipline,” pained, afflicted, shedding tears, departed having uttered a cry of distress.
Then the Lord addressed the monks, saying: “Monks, there are these two cases of manifestation of a serpent’s true nature: when he indulges in sexual intercourse with a female of his own species, and when he falls asleep in confidence. Monks, these are two cases of manifestation of a serpent’s true nature. Monks, if an animal is not ordained, it should not be ordained; if it is ordained, it should be expelled.”

As you can see from the Vinaya narrative above, at least
some nāgas are animals, but I'm not sure if it's the case that all of them are.
For example, are the nāga followers of Virūpakkha in the Cātummahārājika heaven animals? Or are they devas of serpentine form? I've never seen any explicit statement either way, but I think the Theravāda position
ought to be that they are devas, for at the Third Council the Theravādins rejected the claim of the Andhakas that there might be animals living in the heavenly realms.
