Essay:
Looking back at the 9 marine invertebrate phyla we have covered, you will choose one of the phyla and produce an essay. In
this essay, you will describe and discuss the characteristics and physiological adaptations members of the phyla exhibit for the
following:
o Feeding (diet, special structures)
o Environment (benthic, pelagic, intertidal zone, deep sea, etc.)
o Locomotion (planktonic, tube feet, arms, tentacles, sessile, etc.)
o Reproduction (sexual or asexual, broadcast, larval forms, internal or external, etc.)
Within each phylum, there may considerable morphological and physiological variation in the approach to these life problems.
Discuss the variation among organisms within a phylum. For example, Portuguese Man-of-War are vastly different than other
members of their phylum like coral and anemone. Finally, what major characteristics of this phylum distinguish it
evolutionarily from other phyla? Think about germ layers, symmetry, presence of body cavities, nervous systems, etc.
Your essay will be graded according to the following:
o Phylum identified
_____ / 2pts
o Feeding habits and structures of phylum members identified and discussed
_____ /6 pts
o Environment identified
_____/ 6 pts
o Locomotion structures identified and described
_____/ 6 pts
o Reproduction strategies identified, described, with specialized structures included
_____/ 6 pts
o Diversity among phylum members discussed as it pertains to the above four characteristics. Additionally, consider
germ layers, symmetry, organization level and complexity of systems
_____/ 10 pts
o Minimum of 600 words, typed
_____/ 4 pts
TOTAL __________ / 40 points
