The Adventure of Link Manual Comment
Geldarms are very tall bugs that stretch up directly into the air, waving in the wind of the desert regions it lives in. Geldarms emerge from below the surface and retreat into the sand if their body is struck with Link's sword. As the monster lowers itself, a few slashes with the sword to its head  will be more than enough to destroy the Geldarm. They are more of a path-blocking nuisance than a dangerous foe, but the rocks that fly around in the desert are hard to avoid when dealing with these enemies.
- Its name is similar to that of the Geldman, another desert-faring creature. In Japanese, "Geld" is written and read the same as "Gerudo", suggesting a connection between the sand monsters Geldarm and Geldman, and the desert or beach-dwelling Gerudo race featured in later games. This connection is lost in translation. This is the first use of the word Gerudo in the series.
- The アーム (Āmu) in their Japanese name is shared with other enemies such as Moldorms in the original The Legend of Zelda (モルドアーム (Morudoāmu)) and Pincer (ホールドアーム (Hōrudoāmu)), suggesting a relation between these enemies.
