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 don’t get stuck on minute details. Stick to obvious differences.
