Because I'm so sensitive, I'm easily affected by changes in the environment. Scientists often watch changes in my physiology, distribution areas, or reproduction rates to observe relationships between the environment and living things, including relationships between the environment and man.
因為我很敏感，外界環境一有變化，我就會受到影響，因此學者們常透過我在生理上、分佈地區或是生殖的增減等變化，來觀察生物與環境的互動關係，也包括人與環境間的關係。
