Invertebrate Zoology Lecture Notes Ppt New
Here is some text that could be used for an "Invertebrate Zoology Lecture Notes PPT" on a new topic:
Slide 5: Phylum Cnidaria
Title: Phylum Cnidaria: The Stingers
Slide 7: Porifera Body Architectures
- Old View (Morphology-based): Worms were grouped together (Aschelminthes).
- New View (Molecular-based): Ecdysozoa (molting animals) vs. Lophotrochozoa.
- The PPT Impact: A new PPT will show the split of Arthropoda into Pancrustacea & Myriochelata. An old PPT still calls "insects" distinct from crustaceans (spoiler: insects are terrestrial crustaceans).
Slide 4: Cnidarians (Phylum Cnidaria)
Characteristics of Invertebrates
