|How to Hide in the Ocean|
In the three-dimensional ocean, some creatures live on the sea floor, but many live and move about in the water column. Having a body form that is hard to see or detect helps many ocean dwellers avoid being eaten by hungry predators. However, many predators have evolved some of the same adaptations which help them approach their prey without being seen. During this activity students will learn that some of the adaptations for hiding in the ocean include: small size, transparent body, cryptic coloration, disruptive coloration, mimicry of surroundings, and bioluminescence. Students will observe and discuss the advantages of camouflage and then try their hands at designing a well-camouflaged fish. Students will also be introduced to keywords such as camouflage, countershading, transparent, opaque, wavelengths of light, and photophore.
