Kate Winslet’s Avatar Sequel Character is Part of the ‘Sea People’

[Crickett]

So, does anyone else think the sea people are going to be a completely different species?

Absolutely possible, to be honest I still can't imagine why/how part of the plot is going to happen underwater or how the Na'vi are going to stay there over a long period. New (sub)species would be interesting.

Sounds like it to me. The Na’vi seem pretty attached to the land and the trees in a way that’s definitional to their species? And if the “Sea People” speak a sort of sign language, that also points away from Na’vi, I suppose. It makes sense that from the Na’vi perspective, members of different species are given these euphemisms (Sea People, Sky People, etc).

From a world-building perspective, you’ll eventually need other sentient, humanlike species beyond just the Na’vi to really expand and grow the universe.
