1. Animal Diversity… to the EXTREME!

2. Objective Let’s get excited about animal diversity!
Extremes and Limits
Greatest! Strangest!
Most dangerous!
Biggest, smallest, most colourful!

3. Your Task Work with a partner
Take one of the invertebrate phyla or Chordata classes and highlight the EXTREMES and LIMITS of that phyla!
Lottery for your choice of phyla

4. EXTREMES and LIMITS Highlight the… Biggest Smallest
Most dangerous (to…?)
Most colourful
Grossest? Most Beautiful?
… your choice!...

5. EXTREMES and LIMITS This is for FUN!
We are establishing the limits of reality and thus establishing a “scale” to measure with

6. Example – Phylum Mollusca
The largest…
The giant squid!!! Architeuthis
Can grow up to 13m (43 ft) in length… or 18m?
Video:
The colossal squid Mesonychoteuthis hamiltoni
Can grow up to 12-14m… or 20m?

7. Phylum Mollusca Smallest? Snail: Ammonicera rota
0.02 inches in length!
50 of them end to end would measure 1 inch
Not it…. But still small ->

8. Phylum Mollusca Most beautiful? Sea Slugs! (Nudibranchs)
Dendronotus diversicolor
Dall’s denodrotid (Dendronotus dalli)
Spanish Shawl Nudibranch

9. Phylum Mollusca
Watch for lies!

10. Phylum Mollusca
Smallest? Ugliest?
You get the idea…
