Question

make a list, or table, to distinguish among three classes oc cnidarians (Anthozoa, Hydrozoa, Cubozoa).

with respect to

1) life cycles,

2) anatomical complexity,

3) morphologicsl specialization,

4) physical integration,

5) extent of coloniality versus solitary lifestyles,

6) any other traits that you think distinguish among them.

Also discuss the pros and cons for the hypothesis that anthozoans are the earliest-evloving lineage. Which class do you think is ancestral and which do you think is most derived and why? Thank you!
