Questions 9-12 concern general information about each of theinvertebrate phyla we discussed this semester. If none of thechoices are appropriate, type ‘not applicable’.
9. Phylum Chaetognatha (6)
Highest level of organization (cellular, tissue, organ)
Type of symmetry (asymmetry, radial symmetry, pentamerousradial symmetry, bilateral
symmetry)
Number of germ layers (diploblastic, triploblastic)
Type of body cavity (acoelomate, pseudocoelomate,coelomate)
Development pattern (protostome, deuterostome)
Feeding method (filter feeder, suspension feeder, depositfeeder, predator, herbivore)
