Aims

• Describe the variety and nature of microscopic animals which occur in marine environments.
• Describe the variety and nature of a range of different types of marine plants.
• Describe the variety and nature of a range of different types of cnidarians and marine worms.
• Describe the variety and nature of arthropods in marine environments.
• Describe the variety and nature of Molluscs in marine environments.
• Differentiate between different classes of Echinoderms and selected families within those classes.
• Describe the shared characteristics and distinguishing features of a selection of different species of non-bony fish.
• Describe characteristics of bony fish, including anatomy, physiology and behaviour.
• Differentiate between different families of bony fish.
• Describe the taxonomic characteristics of groups of marine animals including reptiles, birds and mammals.

What You Will Do

• Draw a table to compare three different phyla of marine protists.
• Explain the differences between sponges, krill and plankton.
• Produce a table that compares the characteristics of the three different types of algae.
• Explain the difference between seaweed and seagrass.
• How important are marine plants to the survival of marine animals?
• Explain features that distinguish different types of worms apart, including:
  • Flatworms
  • Ribbon Worms
  • Segmented Worms
  • Peanut Worms
• Present a report on research on the Cnidarians.
• Explain the formation of coral reefs. Why are they considered one of the most biologically productive environments?
• What are the advantages of the arthropod's body structure compared to the structure of the less complex animals studied so far in this course?
• Research the living environments of one local arthropod and consider how its body structure and feeding mechanism is adapted to its environment.
• What limitations in lifestyle and behaviour might be imposed by the structure of arthopods?
• Differentiate between cephalopods, gastropods and bivalves.
• Describe the feeding and defence mechanisms of two different molluscs.
• Describe the advantages and disadvantages of the echinoderm's radially symmetrical body.
• What are the feeding, breeding and defence characteristics of echinoderms?
• Select 3 echinoderms and describe their method of reproduction.
• Describe the sensory and behavioural adaptations that sharks and rays use for defence and feeding.
• Do sharks deserve their reputation as maneaters?
• What are the main differences between sharks and rays, and what are main benefits to them of these differences?
• Describe the relationship between a particular kind of lamprey (ideally, one found locally) and its host, considering who benefits and/or who does not, and why.
• List three families of local bony fish.
• Briefly describe the biological characteristics of three fish families:
  • structure
  • feeding
  • colouration
  • reproductive
  • defense mechanisms
• Discuss the behavioural characteristics of the three families you researched:
  • territorial behaviour
  • migration
  • schooling
  • reproductive behaviour
• Draw and describe the gills of bony fish, and explain their function.
• What families of fish are characterised by their habit of sitting perched on their lower fins?
• What are the special adaptations of fish and other marine organisms that live in the mid to deep zones of the ocean?
