The Shanghorn was a creature found on several different planets (or several creatures with the same name).
Venusian Shanghorn Edit
Two different types of creatures were known as Shanghorns on Venus.
One type was a large, rhinoceros-like creature with two horns. They were placid herbivores which could be easily put to sleep with music. Vepaja controlled a herd of them to attack Amtor, but Henry Gordon Jago, George Litefoot, and Felina sang "God Rest Ye Merry, Gentlemen" and stopped the stampede. (AUDIO: Voyage to Venus) There was a Thraskin proverb about trusting a Venusian Shanghorn with your perigosto stick. (TV: The Green Death)
Another type was an aquatic, shark-like creature with sharp fangs. The Venusian artist Radico Harstel created The Physical Impossibility of Getting a Shanghorn into a Glass Tank using a dead Shanghorn. (PROSE: The War of Art)
