Quiz #5b – Life Cycles

 

1. CRABS:  Keep in mind that there are multiple stages in the crab development.

 

2. TUNICATES: The “s” did not Xerox properly, so the first picture should read, “swimming tadpole larva”

 

3. STAR FISH:  Remember that the first few stages are bilaterally symmetrical and that the last adult stage is 5 part symmetry.  Very cool.

 

4. GASTROPOD:  The “veliger larva” looks much like a sea snail.
