RATIONALE:

A knowledge of the zoology of vertebrate animals and practical experience in identifying and dissecting these are fundamental to the education of an animal biologist.


SYNOPSIS:

As humans are vertebrates we have a special interest in this subphylum of the Phylum Chordata. This unit teaches the classification, morphology, anatomy, function and lifestyle of lower chordates and vertebrates. Topics include the classification and natural history of the Urochordata, Cephalochordata Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves and Mammalia, together with comparative study of major organ systems.


OBJECTIVES:

On completion of this unit students will be able to demonstrate:

  1. an understanding of the classification, morphology, anatomy, function and life-style of vertebrate animals;
  2. skills in identification and dissection of vertebrates.

OTHER REQUIREMENTS:

A neat, well-organised, comprehensive and accurate
record of practical work must be kept.  Marks will be
deducted for unsatisfactory work.
Students are expected to participate actively in all
of the practical/tutorial classes in this unit.
Exemption in up to 20% of practical classes may be granted
where documentary evidence is provided which gives
good reason for absence.

i     an Examiner may grant an extension of the due date of an
      assignment in extenuating circumstances;
ii    no assignments will be accepted for assessment purposes
      after assignments or model solutions have been released
      except in extenuating circumstances;
iii   assignments submitted after the due date without any
      extenuating circumstances will attract a penalty of at
      most 20% of the assigned mark for each working day late;
iv    students who submit an assignment after the due date and
      wish to claim extenuating circumstances, must provide
      documentary evidence with the assignment explaining the
      circumstances;
v     the unit examiner shall consider a claim for extenuating
      circumstances and decide on the outcome;
vi    the decision of the Dean shall be final in any dispute
      that may arise in the implementation of these guidelines.
