Research Abstract

Based on the analogy and functional morphology study on exoskeletal terrace ridges of fossil trilobite and extant decapod Pachygrapsus grassipes, its mechanoreceptive role to revalate directivity in touch stimula is clarified. Using the perception mechanisms, the animal could judge the present situation as suitable or not. Trilobites equipped with similar perception mechanisms could monitor the condition of itself against ambient environments, such as against substrate.
