Zoo.121 Diversity of Chordates 3+1

LEARNING OBJECTIVES:

The primary objective of this course is to introduce:
 The course aims to impart in-depth knowledge about the diverse life forms from the
taxonomic positions of Protochordates and Agnatha to Mammalia.
 It will help the students to identify the body plan types of complex chordates and their
systematic organization based on evolutionary relationships, structural and functional
affinities.
 The course will help the students to understand the characteristic morphological, adaptive
and anatomical features of diverse animals.

LEARNING OUTCOMES:

This course will enable the students to:
 Correlate the importance of systematics, taxonomy, and structural organization of
chordates.
 Recognize the diversity of chordates living in varied ecological habitats.
 Critically analyse the organization, complexity and characteristic features of chordates.
