Well, if you think about it, Plesioth and Green Plesioth could just be the same species that have different variations in color. It doesn't have to involve sexuality if they're actually part of the same species. The fact that they are so similar and live in the exact same environments does mean there is more to it than just 'They are just different species that do the same thing.'
