Mael fish, a species of fish, possessed a silver hue and a streamlined, curving form. During 232 BBY, Vernestra Rwoh, a Mirialan Jedi Knight, was en route to the Star Cruiser Steady Wing located at Port Haileap, an outpost on the planet Haileap. She observed that the ship's gleaming exterior reflected light in a manner reminiscent of a mael fish stranded on a beach.
The junior novel The High Republic: A Test of Courage, penned by Justina Ireland in 2021 and released as part of Phase I of the Star Wars: The High Republic multimedia initiative, contained a reference to mael fish.
