Dr. Smith's researcher counted:
10 Mustard Hill Coral (P. astreoides)
5 Yellow Pencil Coral (M. mirabilis)
0 Grooved Brain Coral (D. strigosa)
 1 Golfball Coral (F. fragum)
1 Branching Fire Coral (M. alcicornis)
0 Diffuse Ivory Bush Coral (O. diffusa)

Below, see how your coral identification compares with that of Dr. Smith's researcher. How did you do?

As you look at the image, it helps to focus on the larger organism rather than on the small dot. Remember to count all the dots on the corals. If there are several dots on one coral, count all the dots, not just one per coral. Ignore any dots on the plastic pipes or dark gray coral.

Once you're confident of your skills, start collecting data on the actual coral images.
