體側線(lateral line;lateral line system (LLS);lateral line organ (LLO);側線管系;側線系;側線系統)是壓力感受器官,又稱側線感覺溝,俗稱魚腥線。幾乎所有的、在水中生活的兩棲動物蠑螈或是爪蟾,還有很多水生爬行動物,如鱷魚等,都有體側線。這種細小的感受器官成百上千的排列在身體側邊。在魚類身體側面大於正中,人們可以看見一條清晰的點狀線,故名。體側線感受水流和壓力波。[1]

In this oblique view of a goldfish (Carassius auratus), some of the pored scales of the lateral line system are visible.
鯊魚的體側線

體側線的組成有兩種,一是勞倫氏壺腹(Ampullae of Lorenzini),二是神經丘(Neuromasts)。後者是眾多的感受細胞,它們的感覺毛在膠質狀的壺腹帽(Cupula)中。水流造成壺腹帽的偏移,產生神經衝動。
