记忆联想：exo-像“外”，skeleton是“骨骼”，合起来就是“长在身体外面的骨骼”，比如虾、蟹的硬壳。
语域：formal 常见场景：biology textbooks、zoology lectures、nature documentaries 该词是动物学/生物学专业术语，多用于学术文章、教材、科普读物或纪录片等正式或书面语境；日常口语中较少使用，更常说 shell 或 outer skeleton。
只有 skeleton 与 exoskeleton 完全押韵（skeleton: /ˈskɛlɪtən/）。exotic 虽以 exo 拼写，但读作 /ɪɡˈzɒtɪk/；exodus 也以 exo 开头，读作 /ˈɛksədəs/，都不是 exo- 的读音；skeletal 以 skel 开头，但结尾是 /təl/，不是 /tən/。
