Sarah Smith, who is in 2nd grade learned about human anatomy in her elementary school. After the class, Sarah played with her volleyball at her garden, and saw a few butterflies are on her hat. She asked her mother if butterflies are vertebrates. Sarah’s mother, Amanda, said butterflies are not vertebrates because they are insects and they are part of the arthropods.

He told Sarah that the paired limbs of the Vertebrate like his dog’s limbs arose by the functional transformation of two pairs of the gills. Sarah learned that there are several types of vertebrate such as aquatic vertebrate animals and land dwelling vertebrates like Sarah and her family. Moreover, the digestive tract which can determined overall size of organism might be short or long based on their feeding habits among numerous
