Smell- some animals ie. dogs have greater sense of smell then humans. Sight- varies across species- different evolutionary process have shaped eyes differently for the multiple purposes it needs to serve. Nocturnal animals have larger lenses to absorb more info and light then humans would because they function at night. Taste- fruit fly has taste sensors in their legs, humans on our tongue. Sound- bats use sonar and they can identify objects form a great distance is they detect noises and movement form a great distance.
