The shape of the seal is that of a Chamorro sling stone used as a weapon for warfare and hunting.

Its bent trunk attests to a people which have been tested by famine, natural calamities, genocide and foreign wars but have continued to endure as a race.

The seal also includes a flying Proa, a seagoing craft built by the Chamorro people, which was fast and agile in the water requiring great skill to build and sail.

The Hagåtña River channel, where fresh water rushes out to interact with the ocean, symbolizes a willingness to share the resources of the land with others.

Also in the background, "Ritidian" juts majestically into the endless waters of the sea, portraying the people's faithful commitment to passing their proud heritage, culture, and language to the endless sea of future generations.
