this is no surprise since they are a perfect match
while the giant flightless ostrich has poor senses of both smell and hearing the zebra has acute senses of smell and hearing
on the other hand the zebra has terrible eyesight while the ostrich has excellent eyesight enhanced by its seven foot long which enables the ostrich to see far into the distance
in this way each makes up for the other deficiencies
as a result the animals are far safer together than they would be apart
ostriches can see predators such as lions from far in the distance while zebras can smell or hear other as they approach
