What is the weakest of 5 senses for Rhino?

The weakest sense of a rhinoceros is its eyesight. Despite their massive size, rhinos have relatively poor eyesight and are known to approach objects, or even other rhinos, very closely before realizing that they are not far away obstacles but other entities. However, it is important to note that rhinos have excellent hearing, smell, and touch, which allows them to compensate for their limited vision.
