Objectives: 

- Learn about the differences between the phylum
- Learn how to handle live animals

#Introduction to Shellfish Biology 
				
In today’s lab, you will have the opportunity to observe animals from four different phyla and begin to think about what unites animals from each of these groups.  Today’s lab is also designed to get you comfortable in the laboratory, practicing skills and techniques we will use for the rest of the quarter.  This includes observing and drawing live and preserved animals, using microscopes and micropipettes, thinking critically, and asking questions (do lots of this!).  

###Station 1: *Cnidarians*
	
#####1 These animals are all from the phylum *Cnidaria*.  What do you think are three characteristics that might define this phyla? 
 

 

 

 

 

##### List as many organisms from this phylum as you can.

###Station 5: Microscopy
#####6 Look at the organism on the dissecting scope. What phylum does this organism belong to? How many different pairs of appendages do you count?  Are any of the appendages modified? 
&nbsp;

&nbsp;

&nbsp;

&nbsp;

&nbsp;

###Station 6: Live Tank
#####7 List all phyla represented in the live tank. How can you tell?
&nbsp;

&nbsp;

&nbsp;

&nbsp;

&nbsp;

#####8 What unites all the animals you saw today?  Do you think that shellfish is a biologically meaningful term?
