The breakdown of the Latin roots of Campeloma decisum are as follows:

campel=champion of the field, victor..........oma=tumor
decis=to cut off from all other
**Translations derived from Latin Translations and Word Empire.

It is interesting that Campeloma decisum has such a contradictory name, with its genus root name, campel, creating a positive visualization, and its species root name, decis, creating a negative visualization.  However, according to Word Empire, the species root name is actually referring to cutting off other possibilities to come to a correct judgment of its classification (since Campeloma decisum is easy to classify based on its characteristics).
