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.
