Which specific sensory organ's passages are noted as being larger than the entire brain of the white rhinoceros?
Answer
The olfactory passages within the muzzle
Despite possessing imposing physical size, the white rhinoceros compensates for relatively poor eyesight by developing extremely acute senses of smell and hearing. The sense of smell is highlighted as arguably the most vital tool for its survival and daily functioning. This superior chemical perception is evidenced by the anatomy of its muzzle, where the olfactory passages responsible for processing scents are developed to such an extent that they are actually larger in volume than the animal's entire brain. This development is critical for tasks such as securing territories and locating mates through scent-marking.
