Ostracod Inquiry
Ostracod2-Combo.jpg

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.
