What do the Greek roots *potamos* and *trygon* summarize in the Genus name *Potamotrygon*?
Answer
Stingrays that live in rivers
The genus name, *Potamotrygon*, is constructed from two specific Greek components that succinctly describe the defining ecological feature of this group of fish. The root *potamos* translates to 'river,' and *trygon* translates to 'stingray.' Their combination directly summarizes the group's defining feature: these are stingrays specialized for and confined to riverine environments, setting them apart taxonomically from stingrays inhabiting the sea. This naming convention provides an immediate descriptive summary of the genus's habitat specialization.
