  When you think of fish, what comes to mind? Maybe you think of pet goldfish,
movie characters like Dory or Nemo, or trout in a local river. One of the
things that all of these fish have in common is patterns in their skin. Nemo
sports black and white stripes in his orange skin, and trout have spots. Even
goldfish have a pattern -- it's just plain gold (and kinda boring). Why do some
fish have stripes, others have spots, and others have plain patterns? It turns
out that this is a tricky question, so scientists need tools from several
subjects to answer it. In this paper, we use biology, math, and computer coding
to help figure out how fish get different skin patterns.
