Rhinomusca flies are often found in and around the filarial lesions, but also easily draw blood through the skin itself. Touch a rhino with a feather, and it will immediately respond. Rhinos have myopic vision, but this is no handicap, but merely that they don't need their eyes in view of the sophistication of their other senses. For instance, they have phenomenal hearing. Our orphaned rhinos can detect the approach of another rhino half an hour before the animal actually becomes visible.
Chemistry plays probably the most significant role within a rhino's life.
By kicking their dung with the hind feet, they demarcate boundaries and territory and leave their specific scent trail on the ground for others to know where they have gone. By squirting their urine against shrubs and bushes they advertise their rank and status through hormones, in the case of the females, also indicating estrous cycles and in the case of-the males alerting others to dominance and rank which are important parameters for breeding. The memory of a rhino is also phenomenal. Having carefully and meticulously explored their surroundings only once, a new orphan can then take it at a gallop and never collide with any obstacle, moving swiftly and surely simply by memory and scent. The role of rhinos within the environment is a very important one.
