					DELIGHTFUL DOLPHINS
         • Dolphins are beautiful
           mammals of the
           ocean. They are very
           interesting creatures to
           study and you will
           learn several amazing
           facts about these
           delightful creatures.
DOLPHIN FEATURES
        • One feature that a
          dolphin has is smooth,
          rubbery skin. Another
          feature a dolphin has
          is a blowhole. This is a
          hole on top of its head
          and is used for
          breathing. A dolphin
          also has flippers, a fin
          and a tail.

CHARACTERISTICS
        • Dolphins are very friendly
          and playful. They like to
          swim fast in the ocean.
          They like to play tag and
          dance on their tails across
          the water’s surface. They
          also like to ride the waves
          made by motorboats.
DOLPHIN NUTRITION
        • Dolphins eat fish. A
          dolphin can find fish in
          the ocean even if it’s dark.
          They use echolocation.
          Echolocation is a method
          by which a dolphin sends
          out sound waves which hit
          an object, such as fish or a
          rock, and then an echo
          bounces back letting the
          dolphin know what the
          object is.
DOLPHIN SOUNDS
      • Dolphins make lots of sounds.
        Some sounds are for
        communication.Every dolphin
        makes a special whistle sound. If
        a baby dolphin strays, its mother
        gives her special whistle and the
        baby whistles back and then they
        find each other. Dolphins also
        make loud clapping noises with
        their jaws. This happens when
        dolphins get angry. They also slap
        the water hard with their tails.
DOLPHIN BUDDY SYSTEM
          • Dolphins swim in large
            groups called pods. Within
            these groups, dolphins
            look after one another.
            When danger approaches,
            they send signals. If a
            member of the group is
            injured or in distress, they
            will push it to the surface
            so it can breathe. If a
            shark comes by, the
            dolphin circles around it to
            scare it away. If that
            technique doesn’t work
            the dolphins will fight.
DOLPHINS TO THE RESCUE
            • Dolphins are very helpful to
              people. Dolphins have saved
              people from death. They have
              pushed people away from
              sharks, shoved them onto shore
              when they were drowning and
              even kept their boats from
              sinking. Dolphins are also
              helpful to fishermen. The
              dolphins chase the fish into the
              fisherman’s net and many fish
              are caught.
DOLPHIN TRAINING
       • Dolphins can be trained to
         perform various tasks.
         Dolphins are trained by hand
         signals. Trainers use hand
         signals to communicate with
         dolphins. They can be trained
         to jump out of water and do
         flips in the air. Dolphins can
         fetch for balls, frisbees, or
         rings by following signals.
DOLPHIN VARIETY
       • There are many different
         kinds of dolphins. Some
         types are common
         dolphins, bottlenose
         dolphins, hourglass
         dolphins, dusky dolphins
         and amazon river
         dolphins. These dolphins
         have their own unique
         features. They all are
         beautiful mammals of the
         sea.
