名詞 定義　
total length The greatest length of the whole body between the most anterior point of the body and the most posterior point, in a straight line, not over the curve of the body. Sometimes, when there are two equal lobes, the caudal rays are squeezed together and their tip is taken as the most posterior point (excluding the caudal filaments), or the longest lobe is squeezed to the midline (maximum length or extreme tip length). Also an imaginary line may be drawn between the two lobe tips and length to its mid-point taken as the most posterior point (total auxiliary length or bilobular length). Usually the tip of the most posterior lobe of the fin in normal position is taken as the posteriormost point (total normal length or natural tip length). Total length is used by taxonomists in Myxini, Petromyzontiformes, usually in Elasmobranchii and sometimes in other fishes. Standard length is usually employed with Teleostei. Abbreviated TL. 　
全長 身體最前端與最後端間直線而非彎曲部分的最大長度。當有二個等長的上下葉時，尾鰭鰭條會一起被擠壓，而將其末端被作為最後端 (除了絲狀尾)，或最長的葉被擠壓到中線 (最大體長或末端長)。 也可在上下葉頂點間想像一條中央線來作為最後端(總輔助長或上下葉長)。通常是以在正常位置的鰭葉頂端作為最後面的點 (總自然長或自然末端長)。全長被分類學家使用於盲鰻綱、七鰓鰻目、板鰓亞綱與有時用於其他的魚類。標準體長通常是被用真骨魚類。縮寫為「TL」。
