What physical feature is a primary characteristic of the genus Sander besides the elongated body?
Answer
Large, glassy-looking eyes
Species grouped within the genus *Sander* are characteristically identified by having relatively elongated bodies and, most distinctively, large, glassy-looking eyes. This ocular characteristic is directly tied to the species epithet *vitreus* (glassy). This physiological adaptation provides a significant ecological advantage, enabling members of *Sander* to hunt effectively as crepuscular or nocturnal predators in the deeper, darker, or more turbid water columns where light penetration is limited, contributing greatly to their success in those specific niches.
