絛蟲綱（學名：Cestoda）是一個寄生性扁形動物門的一個綱^[2]^[3]。人們常說的絛蟲其實是多個物種的泛稱。所有絛蟲綱的物種都是寄生蟲，其生活史可能各有不同，但這些物種的成蟲寄生於各類脊椎動物的消化道內，而其幼年期則寄生於其他動物的物種，例如：軟體動物。這些物種自身無消化道，體分節或不分節的扁形動物。

絛蟲的寄生歷程已有很長久歷史：科學家在一塊2.7億年前（二疊紀中期到後期）的鯊魚糞便化石（coprolites）裡發現了多叢絛蟲卵及一條發育中的蚴^[1]。

分類

目前全球約有4000餘種，中國約有400種^[4]。共分以下兩個亞綱：

單節絛蟲亞綱（Cestodaria）
多節絛蟲亞綱（Eucestoidea）

寄生於人體的絛蟲有30餘種，多屬圓葉目（Cyclophyllidea）和假葉目（Pseudophyllidea），最著名的種是引起人類絛蟲病的豬肉絛蟲^[4]。

多節絛蟲亞綱物種的分類已澄清^[5]。以下為現時的分類：

單殖綱 Monogenea
- Amphilinidea
  - Caryophyllidea
    - Spathebothriidea
      - Trypanorhyncha
        假葉目（Pseudophyllidea）
        四葉目（Tetraphyllidea）
        Diphyllidea, Proteocephalidea
        
        Nippotaeniidea
        圓葉目（Cyclophyllidea）、Tetrabothriidea

四葉目、假葉目（因為裂頭絛蟲科，Diphyllobothriidae）及圓葉目（因為Mesocestoididae科）均為並系群。

帶科（Taeniidae）可能是圓葉目之下12個目的最基底^[5]。

The Tetraphyllidea, Lecanicephalidea, Proteocephalidea, Nippotaeniidea, Tetrabothriidea, and Cyclophyllidea are considered to be the 'higher' tapeworms.

海洋中的Trypanorhyncha目有277個已知物種，分為五個總科：Tentacularioidea, Gymnorhynchoidea, Otobothrioidea, Eutetrarhynchidae 和 Lacistorhynchidae.

特徵

成蟲扁長如腰帶，分節，白色或乳白色，體長因蟲種不同可從數毫米至數米不等。由頭節（scolex）、頸部（neck）、節片（proglottid）組成，前端細。頭節上有槽、吸盤或鉤，藉此附著在宿主腸壁上；節片由頸分裂而來，節片由一至數千不等，越往後越寬大；每一節片相當一個體，稱鏈體（stroblius），鏈體是蟲體最顯著的部分，其中至少有一套雌雄生殖器官，其他器官退化，營養靠體表吸收宿主的養料；隨著生殖器官的發育，節片愈後愈成熟，有卵的節片稱為孕節，最後逐節或整段脫落，隨糞便排出宿主體外。

生活史

卵內具有鉤的胚，胚逸出後侵入中間宿主，發育為實心或囊狀的蚴，蚴被最終宿主吞食後，即在小腸內成長為成蟲；例如寄生人體內的豬肉絛蟲、牛肉絛蟲。
