Ostracod Inquiry

This crustacean looks like a "shrimp in a clam shell" and was collected from a pond in Flagstaff, Arizona.
Questions:
- How does this tiny crustacean move?
- Can you think of other types of movement that are similar to the one you see here?
- How does this organism's movement compare to other organisms?
- Can you find any cycles in the video? How do these cycles compare to other cycles you know about?
- What is the advantage to this organism for having a compressed or flattened spherical shape? How does this critter use its shape?
- What else can you find out about this critter?
Meanings:
Ostracod:
ostraco- comes from the Greek word for shell
co comes from the Greek word for "with"
So, ostracod means a critter with a shell.
