Our trout are now in their "parr" stage and are developing distinctive colors and patterns. We have been visiting classes with a slide presentation science-inquiry illustration activity to explore these color adaptations. Our Brown Trout, in particular, are able to change colors to blend in with habitat features, and several classes will be setting up experiments over the coming weeks to observe this phenomenon. Trout are not the only fish that can change color. Flounders, like the one on the right, are masters of this skill.
How do they do it? They use special cells called chromatophores! For a quick intro to fish coloration. You can see chromatophores up-close here. Fascinating stuff!
Fish living in darker locations tend to take on darker colors, but did you know that blind fish turn dark colors, as well? Check out the links in "On-line Resources" if want to know more.
