The Common Error: Depicting the Mola mola with a large, crescent-shaped tail fin (like a tuna or a mackerel). Why It Happens: Early naturalists, including some 18th-century Dutch painters, assumed the fish’s stubby back end was a result of damage, so they "restored" a forked tail. The Correction (Per the Errata List): The sunfish has no tail. Instead, it has a clavus—a scalloped, rudder-like structure formed by the fusion of dorsal and anal fin rays. It looks less like a fin and more like a flattened, fringed baseball mitt. If your illustration has a distinct, separate lobe for a tail, you have failed the Mola Errata List.
At the end of the game, the player with the heaviest Mola wins. Mola Errata List
As of 2025, the Mola Errata List has evolved. It is no longer just a static list of "don’ts." A group of 3D modelers at the University of Zurich are turning it into an open-source digital sculpting guide. Meanwhile, a children’s book publisher was recently forced to recall a title because their sunfish illustration violated Erratum #1 and #3. The Common Error: Depicting the Mola mola with
The list has also expanded to cover the other sunfish species (Mola alexandrini and Mola tecta, the Hoodwinker Sunfish). Each has its own errata profile. As of 2025, the Mola Errata List has evolved
If you are an artist preparing to illustrate Mola mola, treat the Errata List as your pre-flight checklist.
No single official "Mola Errata List" is published by the Guna General Congress. Instead, savvy collectors maintain their own. To start yours:
