2. Introduction
Animal diversity of chordates which includes the study of primitive chordates
collectively known as protochordates also includes study of Amphibian, Reptile,
Aves, and Mammals and comparative anatomy of systems.

3. Syllabus of paper
As per Gondwana University, Gadchiroli Animal Diversity of Chordates has been allotted to
B.Sc sem –III, Paper I
Unit - I
