Candidates should be able to:

1 state that marine organisms can be classified into groups by the features that they share

2 describe the binomial system of naming species

3 state the three domains used in classification 

4 state the main kingdoms of Eukarya found in marine habitats and know the main features used to place organisms into the appropriate kingdom, giving marine examples of each
