1. Shark Anatomy H.S. Bio 2012

2. External Anatomy – (form = function) Shape = fusiform – Olfactory= extremely sensitive Spiracles- efficient respiration

3. Shape – form = function where does the shark fit?

4. Olfactory System of Shark Not connected to mouth or respiration Step 1- water in -incurrent appeture Step 2- olfactory lamellae-series of folds Step 3- info to olfactory bulb Step 4 -info to olfactory lobe on front of brain Step 5- water out –excurrent appeture
