Notes 1 SPI Adaptation SPI Variation Two type of adaptations: (1)Behavioral- (2)Structural- Question: See the insects in the picture below. Is this mainly an example of behavioral or structural adaptation? Can you see them? Press the Right Arrow Button to Advance through the Presentation! (what an organism does) (what an organism is…shape & form of the body) This is mainly showing structural adaptation because these insects have adapted by developing bodies that look like thorns. This is called camouflage
