[3] S. guentheri undergoes diel vertical migration; specimens have been found between depths of 500-1000m during the day and 150m at night.

Additionally, larvae have been found closer to the water surface, limited to depths of 0-100m.

[4] Scopelarchus guentheri is anatomically characterized by having 6-7 dorsal soft rays, 24-29 anal soft rays, 46-51 vertebrae, and pigmentation found exclusively in dorsal and ventral stripes to the lateral line.

The visual system of S. guentheri has been studied via optical and electron microscope, where the retina of the species was described.

[2] The posterior region of the main retina is especially striking due to the symmetry of the rod bundles, and the pigment cells of S. guentheri are triangular in shape,[2] which is distinct from the commonly polygonal shape of other teleost's pigment cells.
