These organisms have evolved unique adaptations to allow them to survive, including mechanisms to prevent drying out, camouflage, hard shells or exoskeletons, adherence to rocks, mechanisms to reflect sunlight, or the ability to trap water. In this design challenge, participants create a creature that lives in the rocky intertidal shore. - +
