Ga-Matoran came in all shades of blue and sometimes silver, and generally had yellow or orange eyes. These water Matoran lived on the shores of the sea, so they had a sleeker build, better lung capacity, and other physical advantages for swimming. All Ga-Matoran were female, whilst most of the other types were composed entirely of males. Most Ga-Matoran tended to be peaceful and friendly, though there were exceptions, such as Dalu. Ga-Matoran culture put the most value on the virtue of Unity and its principle of Purity. In Metru Nui, about half of the Ga-Matoran were teachers and most of the other half were students; the best were promoted to work on protodermis purification. On Mata Nui, they were mostly boaters and fisherwomen.
- Ga-Matoran have been referred to as "water-ladies" or "water-maidens" by the Le-Matoran and Onu-Matoran.
