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
