Overview: A program that introduces students to some of the major differences between fish, amphibians, reptiles, birds and mammals. Students will understand the differences between vertebrates and invertebrates, and how humans fit into the environment.he level of differentiation we are going to examine in this program is the broad taxonomic classification class.. The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds.
Tortoises and turtles are both reptiles from the order of Testudines, but in different classification families. The major difference between the two is that tortoises dwell on land, while turtles live in the water some or nearly all of the time.
