       mates, identify other members of its species, detect
       predators, or find its way home. A sense of taste
       involves direct contact with food in order to test
       if it is a tasty meal that is safe to eat.




             2  FRUIT BAT
            While insect-eating bats depend on
            their acute sense of hearing to detect
            prey, larger fruit-eating bats use their
            excellent senses of smell and vision to
            find food. Also called flying foxes, they
            live in tropical areas where there is a
            constant supply of fruit. Some species
            of fruit bat feed on flowers, nectar, and
            pollen, also found in tropical areas.
                                                                        2


             3   KIWI                                                                                         3
            Native to New Zealand, this nocturnal,
            flightless bird has poor sight, but,
            unlike most birds, it has a great sense
            of smell. The kiwi has two nostrils at the
            tip of its long beak. As it looks for food,
            the kiwi pushes its beak into the soil to
            sniff out worms, beetle larvae,
            centipedes, and other juicy food items.


             4   TAPIR
            A tapir lifts its upper lip to expose the
            opening of its Jacobson’s organ,
            located in the roof of the mouth, which
            enhances the ability to smell and taste.
            This action, called a flehmen response,
            draws in airborne scents. It is also
            performed by lions and some other
            mammals, and is used mainly to pick
            up smells given off by potential mates.


             5   MOTH
            Insects use the two antennae attached                                                                                  5
            to their heads to detect smells and
            tastes, as well as to touch. Some male                           4
            moths have feathery antennae that are
            supersensitive to pheromones
            (chemical signals) released by females,
            often hundreds of yards away. As they
            fly at night, males pick up the scent trail
            and follow it to find a potential mate.
