Document Summary

If you see a caterpillar covered in yellow and red spines, you would suspect that it: has a strong chemical defense. Monarch butterfly caterpillars are not good to eat because they contain cardiac glycosides (terpenoids). They way they acquire the toxins is known as: sequestering. Mullerian mimicry is when: a number of animals, non-related and all armed with some defence, look like each other. Skunks are black and white because this colour pattern makes them visible and stand out during the night. The head of a chipping sparrow has a black line through the eye and a white stripe about it. But if a bird sees one and pecks at it, the moth open its wings and bright patterns suddenly appear and startles the bird. American bitterns have vertical markings on their breast because the stripes: allow bitterns to hide in cattail marshes.
