Compared to smell and hearing, which primary sense is considered the least developed faculty in wolves?

Answer

Eyesight

Wolves possess a remarkable array of sensory capabilities essential for their survival, notably an acute sense of smell, estimated to be about 14 times better than that of humans due to a much larger olfactory epithelium surface area, and excellent hearing. However, when evaluating their sensory suite, eyesight is noted as being the least developed faculty among these primary senses. Despite this relative weakness, their eyes are yellow and possess the ability to produce a noticeable greenish-gold eye shine during nighttime conditions.
