In comparison to *Sander vitreus*, how is the body profile of the sauger (*Sander canadensis*) generally characterized?
Answer
Shorter and stockier in comparison.
When directly comparing the physical builds of the walleye (*S. vitreus*) and the sauger (*S. canadensis*), key differences in body proportions emerge. While the walleye is described as possessing an elongated and streamlined shape conducive to quick pursuit bursts, the sauger is typically observed to be shorter and stockier. This difference in profile, alongside differences in barring and eye opacity, allows experienced observers to distinguish between the two similar species even when standard field marks might be obscured or difficult to observe under poor conditions.
