           1    What is the difference between a vertebrate

               animal and an invertebrate animal?                                                      crab

           2   Which of the animals in the pictures

               are vertebrates? Name another

               vertebrate you know of.

           3   Which of the animals in the pictures are
               invertebrates? Name another invertebrate

               you know of.

           4   Which of the invertebrates in the pictures

               have an exoskeleton?

           5   The skeleton of a vertebrate grows, which allows

               the animal to grow. The exoskeleton of an                                          crocodile
               invertebrate cannot grow. How do you think an

               invertebrate with an exoskeleton is able to grow?
