This
video involves an interview with marine biologist Dr. Roger Hanlon as he
describes what is so unique about octopus (and squid) camouflage.
- What did
the octopus do to look bigger?
- Octopuses
don’t have bones or hard outer shells for protection. Why would this lack of
protection make it so important for them to hide?
- Does the
octopus hold still when it is trying to blend in, or does it move? Do you think
that octopuses blend in better when they hold still or when they move?
- What is so
unique about octopus skin? Do you think our skin looks like that under a
microscope? Why or why not?
Camouflage Vocabulary
Camouflage has some specific vocabulary words when one describes how something or someone can be hidden:
Shape
- Definition: The outline or area of an object
- Example: An orange has a round shape.
- Perform: How can you change your shape?
How can you change the shape of your hand to look like different things?(think shadow puppets)
Texture
- Definition: The way something feels using your sense of touch or how you think it looks using sight.
- Example: The texture of the teddy bear is soft. The texture of the desk is smooth.
- Perform: Point to something near you that has smooth texture.
Point to something near you that has a rough texture.
If you were looking at something on paper (rug, cloud), how would you know what the texture is?
Size
- Definition: How big or small something is; how much space it takes up.
- Example: A balloon starts out small but when air is added it, it gets bigger in size.
- Perform: If you wanted to look like you were growing in size, what would you do?
How could you make yourself look smaller in size?
Color
- Definition: The pigmentation of something; the way something appears based on how it reflects light.
- Example: The color of most salad is green; apples can be green, red, or even yellow in color.
