    簡單來說,側線器官(lateral line organ)就是指魚和兩棲動物感覺器官,主要用來偵測水中的壓力變化~~

    In fish, the lateral line is a sense organ used to detect movement in the surrounding water. Lateral lines are usually visible as faint lines running lengthwise down each side, from the vicinity of the gill covers to the base of the tail.

    在魚體內, 側線是用來偵測周遭水的流動的感覺器官。側線通常是可在兩邊看見的縱長的線, 從鰓蓋子的近處到尾鰭的基部。

    The receptors in the line, known as neuromasts, each consist of a group of hair cells, whose hairs are surrounded by a protruding jelly-like cupula, typically 1/10 to 1/5 mm long. The neuromasts are usually at the bottom of a pit or groove, which is large enough to be visible. Teleosts and elasmobranchs usually have lateral-line canals, in which the neuromasts are not directly exposed to the environment, but communicate with it via canal pores. Additional neuromasts may appear individually at various locations on the body surface.

    感受器官在線, 以neuromasts 著名, 每個包括一個小組毛細胞, 頭髮由一推出的似果凍般的cupula

    圍攏, 典型地1/10 到1/5 毫米長。neuromasts 通常是在坑或凹線的底部, 是足夠大的是可看見的。Teleosts 和elasmobranchs 通常有側向線運河, neuromasts 直接地沒暴露於環境, 但聯絡與它通過運河毛孔。另外的neuromasts 也許單獨地出現在各種各樣的地點在身體表面。

    The development of the lateral-line system depends on the fish's mode of life. For instance, active swimming types tend to have more neuromasts in canals than on the surface, and the line will be further away from pectoral fins, presumably to reduce the "noise" generated by fin motion.

    側向線系統的發展取決於生活魚的方式。例如, 活躍游泳類型傾向於有更多neuromasts 在運河裡比在表面, 並且線將是據pectoral 飛翅, 據推測減少"噪聲" 由飛翅行動引起。

    Uses of the lateral-line system include collision avoidance, orientation relative to water currents, and predation. For instance, blind cavefish have rows of neuromasts on their heads, which could be used to precisely locate food without the use of sight, and killifish can sense ripples caused by insects struggling on the surface of the water. Experiments with pollack have shown that the lateral line is also an key enabler for schooling behavior.

    對側向線系統的用途包括碰撞退避、取向相對水潮流, 和掠奪行為。例如, 盲目的cavefish 有neuromasts 列在他們的頭, 能被使用精確地找出食物沒有對視域的用途, 並且鏘魚能感覺波紋由昆蟲造成奮鬥在水的表面。實驗用綠鱈表示, 側向線並且是一關鍵enabler 為教育的行為。

    以上除了第一段是我自己翻譯的以外,其他是用網路上專業翻譯網站systransoft(http://www.systransoft.com/index.html)所翻譯的,有點不合中文文...
