Fish coloration and camouflage

Today we finished talking about symbiotic relationships including commensalism, parasitism, and mutualism.

Then we talked about fish coloration and camouflage. Some of the tricks these fish have up their fins to blend in or advertise or trick predators are quite ingenious. One of my favorite organisms is the nudibranch - basically a slug that lives in the ocean. These soft squishy slimy critters would make excellent snacks, but they are all poisnous! They have warning coloration to let would-be predators know that they would not taste good at all. You can click here for a National Geographic Article about nudibranchs.

Conservation Report - Can you see me? Is a link to an awesome website with many examples of amazing animal camouflage - some on land and some in the sea. Check it out!

Computer Lab Etiquette

You are in the computer lab to do work for this class. If you are not doing work, then we will have problems.

Do not pack up early. Work until the bell or until MsJ says.

SAVE OFTEN. And if you save to a key, also save it to your number. If you lose it, you will have to do it again.

If MsJ asks for your attention, stop what you are doing and listen to what she has to say.

You may watch videos about your organism through reliable websites.

You may listen to music through the computer if you have your own headphones. Rule1 MsJ cannot hear it. You get one warning. Rule2 Turn it on and listen – no million clicks and constant changing. Take both ear phones out when MsJ is talking.
