Mimicry: The Art of Looking Like Something You're Not
Animal mimicry is the type of adaptation displayed by animals that closely resemble other animals, plants, and even rocks and wood.
You can see a remarkable example of mimicry in the matamata turtle. The shell and skin of this turtle precisely copy the color and texture of a waterlogged piece of dead wood or bark that has settled to a river bottom. As a fish approaches what it perceives to be a harmless object, the motionless turtle snap up its prey in a fraction of a second.
