Animal Diversity… to the EXTREME!
Objective Let’s get excited about animal diversity! Extremes and Limits Greatest! Strangest! Most dangerous! Biggest, smallest, most colourful!
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
EXTREMES and LIMITS Highlight the… Biggest Smallest Most dangerous (to…?) Most colourful Grossest? Most Beautiful? … your choice!...
EXTREMES and LIMITS This is for FUN! We are establishing the limits of reality and thus establishing a “scale” to measure with
Example – Phylum Mollusca The largest… The giant squid!!! Architeuthis Can grow up to 13m (43 ft) in length… or 18m? Video: http://www.youtube.com/watch?v=kjp_jumlO3A The colossal squid Mesonychoteuthis hamiltoni Can grow up to 12-14m… or 20m?
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 ->
Phylum Mollusca Most beautiful? Sea Slugs! (Nudibranchs) Dendronotus diversicolor Dall’s denodrotid (Dendronotus dalli) Spanish Shawl Nudibranch
Phylum Mollusca Watch for lies! http://zapatopi.net/treeoctopus/
Phylum Mollusca Smallest? Ugliest? You get the idea…
