Course overview and learning objective: Marine invertebrates are astoundingly
diverse and interesting, conspicuous in every marine environment on the planet.
MARI202 introduces students to the diversity of marine invertebrate life, with
emphasis on examples from the New Zealand region. The different marine
invertebrate groups are introduced through examination of their evolution and
phylogenetic relationships. Students explore adaptations of invertebrate groups to
the marine environment in terms of comparative physiology and body architecture.
A section on reproduction, development, larval forms and larval ecology highlights
the diversity of reproductive patterns among marine invertebrates. Next we consider
adaptations of invertebrates to specific marine environments (e.g. polar, deep, and
tropical) to demonstrate the diversity of ecological and biological problems and
solutions found in the marine environment. Lastly, we examine the impacts of
humans on marine invertebrates, and vice versa (invasive species, aquaculture,
fisheries, conservation) with an emphasis on how the basic biology of marine
invertebrates influences these interactions.
Specific learning objectives
Students will be able to:
i.
Recognise key marine invertebrate phyla from their external and
internal morphologies and characteristic body plans.
ii.
Explain how form, function, physiology and reproduction of marine
invertebrates are influenced by the marine environment.
iii.
Apply knowledge of marine invertebrate biology to issues around the
aquaculture, fishing, invasive potential and conservation of the
group.
iv.
Identify how the biology of marine invertebrates will influence their
responses to future climate change. MARI202 – Marine

Course Assessment
An understanding of marine invertebrate biology and ecology requires a
lot of factual information about the taxa. It is also necessary to recognize
patterns of adaptations these animals exhibit to thrive in the oceans. A
variety of assessment methods will be used to help guide your study.
10%: Essay on an assigned marine invertebrate topic. Due on Friday
11 August (12:00 noon).
30%: Laboratory and field assignments
-Includes 25% for weekly laboratory work (lab reports and
online quiz) and phylum investigations
- 5% on a report on the analysis of fieldwork
Laboratory assignments will be collected weekly. Online
assessment (via blackboard) will be conducted weekly.
• The Fossil Lab is due Friday 8 September (12 Noon).
• The field assignment is due Friday 29 September (12
noon).
• The phyla sheets are to be submitted Friday 6 October
(12 noon).
10%: 2 hour Practical Exam (THURSDAY 14 September during
practical time) on the first seven laboratories sessions and the fossil
laboratory.
50%: Final Written Exam
Based on lecture material, but some concepts from the practical may
be included.
The essay and field assignments are to be handed into the Department of
Marine Science, placed in the assignment box in Marine Science, Room 154
by the due date. All assignments must be accompanied by a Marine Science
Department assignment cover sheet, available from MARI202 Blackboard.
They must be signed and dated.
***All assignments must ALSO be submitted as a PDF file (or Word
document) to Blackboard (instructions will be provided in the first
laboratory) BY THE DUE DATE. This step is important as it is used as the
time the assignment was lodged with the department***
Late Assignments will lose 5% off the final grade for every overdue day
(i.e. a grade of 67% would become 62% if one day late). Extensions are
normally only given in cases of bereavement or illness (accompanied by
a medical certificate), and are only available before assignment due
dates.

Additional Information
Required Materials: A lab coat is required at all practical sessions. You will
not be allowed to participate without one. New lab coats are available from the
Archway shop in the link next to the main library and also from Road Materials
Workgear (4-6 Forth Street). Sharp lead pencils and an eraser are required.
Dissection kits with fine forceps, scissors, scalpels and probes are required.
Plagiarism Statement: Students should make sure that all submitted work is
their own. Plagiarism is a form of dishonest practice. Plagiarism is defined by
the university as:
Plagiarism is one form of dishonest practice. Plagiarism is defined as copying
or paraphrasing another person's work and presenting it as one's own whether intentionally, or through failure to take proper care. Being party to
someone else's plagiarism (by allowing them to copy your work or by
otherwise helping them plagiarise work for an assessment) is also dishonest
practice.
In practice this means plagiarism includes any attempt in any piece of
submitted work (e.g. an assignment or test) to present as one’s own work the
work of another (whether of another student or a published authority). Any
student found responsible for plagiarism in any piece of work submitted for
assessment shall be subject to the University’s dishonest practice regulations
which may result in various penalties, including forfeiture of marks for the
piece of work submitted, a zero grade for the paper, or in extreme cases
exclusion from the University. The University of Otago reserves the right to
use plagiarism detection tools.
It is your responsibility to be aware of and use acceptable academic practices
when completing your assessments. To access the information in the
Academic Integrity Policy and learn more, please visit the University’s
Academic Integrity website at www.otago.ac.nz/study/academicintegrity or
ask at the Student Learning Centre or Library. If you have any questions, ask
your lecturer.
Communication: When the Department of Marine Science communicates
with you, it will be via your student email address (@student.otago.ac.nz).
Please make sure that you check this address regularly, or that you arrange
forwarding to an address you check regularly.
There will be a student representative chosen by students to take care of
official communications and feedback for your group of students. Make sure
you know him/her.
This paper uses Blackboard, a web-based learning platform, to help manage
teaching and learning in the course. On Blackboard you will find resource
material and notices regarding the course. Please make sure you can access
your own personal Blackboard page (go to http://[email protected]
and login using your university student username and password) and that all
your courses are listed there
