This document contains a CLOZE Reading assignment that focuses on the characteristics of vertebrates and the five common types (fish, amphibians, reptiles, birds, and mammals). All are described with details and examples. The document also contains a reflection assignment (i.e., If not a mammal, what would you be and why?) and a crossword puzzle that helps build and solidify key vocabulary terms. I hope you find this helpful and that it saves you time! Thank you.
