What does the Greek root of the species name *Odobenus* mean, relating to a physical feature?
Answer
Tooth-walker
The species name, *Odobenus*, is derived from Greek etymological roots that directly reference one of the walrus's most noticeable physical characteristics: its tusks. The name translates to mean "tooth-walker." This nomenclature arose from early observations made by naturalists who interpreted the way the walrus used its long, downward-projecting tusks—which are essentially continuously growing, elongated upper canine teeth—to leverage itself or drag its body across ice surfaces, resembling walking aided by its teeth.
