36. Practice ID

37. Fish Drawing Activity Now that you have identified the parts of the fish, it is time to practice identifying the fish you may see on your field study. For each picture you see, take a moment to detail a couple of conspicuous characteristics of the fish. Then make a quick sketch of the fish, including its body shape, fin location, and fin shape. Each slide will be timed, so dont get stuck on minute details. Stick to obvious differences.
