Coloration & Camouflage

We discussed predator prey adaptations - specifically coloration. The first topic is camouflage. Flounder (like the ones pictured) have passive camouflage. Their bodies are patterned and it allows them to blend in with the background. Can you spot the flounder in these photos?

 Active camouflage is when an organism can actually change the color of its skin to match a background or flash colors to confuse predators and prey. Watch the Kings of Camoflage video about cuttlefish in the sidebar for more information.

 The photo above is from this cool website blog that archives photos of all kinds of animals that are camouflaged.
We also talked about other types of coloration like mimicry, flash, warning coloration, advertising, and sexual dimorphism. Students finished the day by reviewing coloration and coloring their own fishes.

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.
