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.
Reptiles are a group (Reptilia) of tetrapod animals comprising today's turtles, crocodilians, snakes, lizards, tuatara, and their extinct relatives.The study of these traditional reptile groups, historically combined with that of modern amphibians, is called herpetology.xtant reptiles range in size from a tiny gecko, Sphaerodactylus ariasae, which can grow up to 17 mm (0.7 in) to the saltwater crocodile, Crocodylus porosus, which may reach 6 m (19.7 ft) in length and weigh over 1,000 kg (2,200 lb).
