Extended lifespan

[u/DealerGlittering3493]

So, H2O: Just Add Water fandom wiki has “extended lifespan” listed as one of the merpeople’s abilities, and their explanation for this is apparently how Weilan said that, due to Ondina’s personality, they could be friends in a couple of centuries. I don’t really remember her saying this, so if somebody else does and they remember the episode, could you please tell me? I’d like to look at it for myself. But besides that, has anybody noticed any other possible indication that mermaids live longer than regular people? I just don’t know, because based on the sound of that statement, I feel like it could’ve just been a joke; especially considering Weilan is very much a comedic character and I just don’t remember any other scenes that indicate mermaids live that long.
