Puna Nui
Puna Nui is an interior sea of the Pua region of Thasusa that is distinguished geographically from Puna Iti by an island and from Djobom Sea by the Djobom Strait. The seas have a difference in salinity as well, leading to a difference in water coloration caused by algae variations.
Three nations have coastlines with the sea. East Pua, West Pua and Xarslasja.
